What is the name of this property?

• Zero Exponent Property
• Zero Product Property
• Commutative Property
• Zero Sum Property

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
