Hard
Find the remainder when p(x) = 2x² + (4)x + (-5) is divided by (x - -1).
Explanation
Explanation
By the Remainder Theorem, the remainder when p(x) is divided by (x - -1) equals p(-1). p(-1) = 2(-1)² + (4)(-1) + (-5) = 2 + -4 + -5 = -7.
PRO TIP
Re-check your working by substituting the answer back into the original question.
