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

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

• 10 and 2

• -2 and 10

• -10 and 2

• -2 and -10

Solve for all values of x by factoring:

x² - 36 = 0

• x = 0 and x = 36

• x = 6 and x = 6

• x = 0 and x = - 36

• x = 6 and x = - 6
