True or false:
The solutions, roots, x-intercepts, and zeros of a quadratic equation 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

What are the zeros of the quadratic function?
y = x² - 2x - 15

• x = -2
  x = -15

• x = -3
  x = 5

• x = 3
  x = -5

• x = 1
  x = -16
