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

(x - 5)(x + 1)

• x^2 - 4x - 5
• x^2 + 6x - 5
• x^2 - 5x - 4
• x^2 - 4x - 4

Factor:
p² - 14p

• p(1 - 14)
