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

Determine the values of

a, b, and c for

the quadratic equation:

4x² – 8x – 3 = 0

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3
