Solving Quadratics with Zero Method

What does it mean to solve a quadratic?

• solve for x by finding the x-intercepts

• solve for y by finding the y-intercepts

• find where they cross

• no solution

To solve a quadratic by graphing, you are looking for the...

• you can't solve with graphing

• y-intercept

• place where they cross

• x-intercepts

We use solving by square roots for a quadratic when...

• the middle x term is missing

• the quadratic is set to 0

• there's an x term and number

• never

Solve the equation using the zero product property.
(x- 9)(x + 3) = 0

• x = 3 or x = 9

• x = 3 or x = -9

• x + -3 or x = 9

• x = -3 or x = -9

Find the zeros of the equation: 
(x+10)(x-2) = 0

• 10 and 2

• -2 and 10

• -10 and 2

• -2 and -10
