Find the remainder when p(x) = 2x² + (2)x + (-4) is divided by (x - 3).
Explanation
Explanation
By the Remainder Theorem, the remainder when p(x) is divided by (x - 3) equals p(3). p(3) = 2(3)² + (2)(3) + (-4) = 18 + 6 + -4 = 20.
PRO TIP
Re-check your working by substituting the answer back into the original question.
