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
2x² + 17x + 21 = 0

• x= ^-21/₂, -17
