16.2 Finding Solutions to Quadratics

What is another word for zeros?
(a)  

• roots

• y-intercepts

• vertex

• axis of symmetry

Identify the x-intercepts

What is the equation for this parabola in factored form? (a)  

• y=(x+2)(x-1)

• y=(x-2)(x+1)

• y=(x-2)(x-1)

• y=(x+2)(x+1)

In factored form you can see the ​ ​ (a)   of the graph easily.

• x-intercepts

• y-intercept

• vertex

What is the factored quadratic equation in the following graph?

• ( x+ 2)(x + 6) = y

• x² - 8x + 12 = y

• (x - 2)(x - 6) = y

• (x - 4)(x + 4) = y

True or false:
The solution, root, x-intercept, and zero of a problem are all the same thing

• True

• False, because the solution and root are the same but the x-intercept and zero are different

• False, because the x-intercept and root are the same but the zero and solution are different

• False, they are all different

• 3

• 2

• 0

• 1
