Your skills in finding the roots will also be the methods you will be using in finding the zeros of quadratic functions.

. Given a general quadratic equation of the form. Use the Quadratic Formula to solve each equation. USE THE PERFECT SQUARE FORMULA.

Examine the equation x² - 3x 2 0. The last step is to find the actual mean by dividing the sum by n. The next step is to add up all the numbers in the set.

The first step is to count how many numbers there are in the set which we shall call n. X²a - 3xa 2 a 0. By using the completing the square method we get x b2a² - b2a² ca 0 x b2a² - b² - 4ac 4a² 0 x b2a² b² - 4ac 4a².

Find the mean of the set of numbers below. Dividing the LHS of the equation with a gives us. X 2 2x 3 0 d.

To better understand the zeros of quadratic functions and the procedure in finding them study the mathematical concepts below.
