What does it mean to "find the zeros" of a quadratic?

• Plug in 0 and solve the expression.
• Factor then set each factor equal to zero and solve to find x-intercepts
• Set the expression equal to zero and solve 
• Factor then set each factor equal to zero and solve to find y-intercepts

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
