True or false:
The solution, root, x-intercept, and zero of a problem 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

Given the zeros below, what is the quadratic equation?

• y=x² +9x -8
• y=x² +9x +8
• y=x² -9x -8
• y=x² -9x-8
