Lesson 7.8 Practice

ax²+bx+c=0  is the standard form of a quadratic equation.

• True
• False

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
