Solving Quadratic Functions

Find the zeros.

• 0 and 4
• 0 and -4
• 0
• -4

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

What are the solutions to this equation? (x-3)(x+2)=0
