The remainder theorem states that the answer when d + 4 is
substituted into the whole equation, the remainder would be the answer divided
by d + 4. Therefore:
d + 4 = 0
d = -4
Evaluating when d = -4:
d^4 + 2 * d^2 + 5 * d − 10
= (- 4)^4 + 2 * (- 4)^2 + 5 * (- 4) – 10
= 256 + 2 * 16 – 20 – 10
= 256 + 32 – 30
= 258
Therefore basing on the remainder theorem, the remainder
would then be:
Remainder = 258 / (d + 4) ---> Answer
