Find the remainder when (5x^{3} + 2x^{2} – 7x – 5) is divided by (x – 2).

  • A.
    -51
  • B.
    -23
  • C.
    29
  • D.
    49
Correct Answer: Option C
Explanation

Using remainder theorem, the remainder when (5x^{3} + 2x^{2} – 7x -5) is divided by (x – 2) = f(2)

(f(2) = 5(2^{3}) + 2(2^{2}) – 7(2) -5 = 40 + 8 – 14 – 5)

= 29
