Question

Find the roots of the following factored quadratic equation.
y= (2x-9) (7x-4)

Answer 1

x = 4.5, 4/7

Explanation:

To find the roots of a factored equation you need to set the y value at 0, that way you can solve for x. Once you solve for x you get two quantities, which can be graphed. These two quantities are where the x intercepts are.
