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

In the equation
y = x² +5x +7, match each leading coefficient with its correct letter

• a=1, b=5, c=7
• a=7, b=5, c=1

Solve by factoring:  4x² + 11x - 3 = 0
