Algebra Help - The Quadratic Formula - For a complete lesson on the quadratic formula, go to . Get the exact algebra help you need with 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to solve quadratic equations in the form ax^2 + bx + c = 0 using the quadratic formula, which states that x = -b plus or minus the square root of b^2 -- 4ac over 2a. For example, to solve the equation x^2 -- 3x -- 8 = 0, since a = 1, b = -3, and c = -8, the quadratic formula states that x = 3 plus or minus the square root of (-3)^2 -- 4(1)(-8) over 2(1). Simplifying on the right side of the equation, x = 3 plus or minus the square root of 9 + 32 over 2, or x = 3 plus or minus the square root of 41 over 2, which is the final answer. Note that students also learn to derive the quadratic formula using completing the square in the first example problem in this lesson.
Discount Formula - - Pre Algebra Help For a complete lesson on the discount formula, go to - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students solve word problems using the "discount" formula, which states original price x rate of discount = discount. Students also solve word problems using the "sale price" formula, which states: original price -- discount = sale price. For example: A tennis racket marked at $110.50 is on sale at 20% off. What is the discount? What is the sale price? Students also solve word problems using the "rate of discount" formula, which is the same as the percent decrease formula: amount of change/ original number. For example: An old video game is marked down from $48 to $18. What is the rate of discount?
Algebra: Formulas From Geometry This lesson consists of providing you with a basic review of the formulas from geometry you will most likely encounter in algebra (and other math classes like trigonometry and calculus). This is NOT a detailed, formal lesson. Formulas and concepts covered include: Angles (complementary & supplementary) Triangles (perimeter and area) Isosceles triangle Equilateral triangle Right triangle The Pythagorean Theorem Similar triangles Perimeter and area formulas for Quadrilaterals (square, rectangle, parallelogram, trapezoid). Some diagonal formulas too, where applicable. Circles (radius, diameter, circumference, area) Cube (diagonal of face, diagonal of cube, surface area and volume) Rectangular box [or Rectangular Parallelepiped] (diagonal of box, surface area and volume) Prisms (Volume) Pyramids (Volume) Cone (slant height, lateral surface area, total surface area, volume) Cylinder (lateral surface area, total surface area, volume) Sphere (surface area and volume)

Dividing Fractions - - Pre Algebra Help For a complete lesson on dividing fractions, go to - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to divide fractions by first changing the division sign to multiplication and flipping the second fraction. For example, to simplify 7 divided by 7/9, first change the division sign to multiplication and flip the second fraction, to get 7/12 x 9/7. Next, multiply the fractions by first cross-canceling, then multiplying across the numerators and across the denominators.

Point Slope Form - - Algebra Help For a complete lesson on point slope form, go to - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to write the equation of a line given a point on the line and the slope of the line, by using the point-slope formula, which states that given a point (x1, y1) and a slope m, the equation of the line can be written as y - y1 = m(x - x1). For example, if a line passes through the point (3, -2), and has a slope of 4, its equation can be written y + 2 = 4(x - 3). From here, the equation can be converted to either slope-intercept or standard form. Note that a horizontal line passing through a given point has the equation y = the y-coordinate of the given point, and a vertical line passing through a given point has the equation x = the x-coordinate of the given point.
Completing The Square - - Algebra Help For a complete lesson on completing the square, go to - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to solve quadratic equations by completing the square. For example, to solve the equation s^2 - 6s + 5 = 0, the first step is put the constant term on the opposite side of the equation as the terms that contain the variables, by subtracting 5 from both sides, to get s^2 - 6s ___ = - 5 ___. Next, the number that goes in each space comes from half the coefficient of the middle term squared, which in this case is half of -6, or -3, squared, which is +9. So a +9 goes in each space, to get s^2 - 6s + 9 = - 5 + 9. The trinomial on the left side of the equation then factors as (s - 3)(s - 3), or (s - 3)^2, and the right side of the equation simplifies to 4, so the problem now reads (s - 3)^2 = 4. Finally, take the square root of both sides to get s - 3 = plus or minus 4, so s - 3 = 4, or s - 3 = -4, and solving each equation from here, s = 7 or -1.

Solving Polynomial Equations - - Algebra Help For a complete lesson on solving polynomial equations, go to - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that the first step in solving polynomial equations is to set the given equation equal to zero, the next step is to factor, and the final step is to set each of the resulting factors equal to zero and solve each equation. This process usually yields more than one solution, so the answer can be written as a solution set. Some of the problems involve factoring a trinomial into two binomials, and some of the problems involve factoring a binomial as the difference of two squares.
Algebra Word Problems - - Math Help For a complete lesson on algebra word problems, go to - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to solve "number" word problems, such as the following. One number is four times as large as another. The sum of the numbers is 45. Find the numbers. Since the first sentence states that one number is 4 times as large as another, the numbers can be represented as x and 4x. Since the second sentence states that the sum of the numbers is 45, the equation can be set up as x + 4x = 45.
