To solve a quadratic by graphing is to find where the parabola crosses the x-axis. We call these the ___. Select all that apply.

• zeroes

• x-intercepts

• solutions

• roots

Choose the correct factored form for the quadratic expression:

x² - 12x + 27

• (x - 3)(x + 4)

• (x - 3)(x - 4)

• (x - 9)(x - 3)

• (x + 9)(x + 3)
