Question

find the remainder when y3 + y2 - 2y + 5 is divided by 3y + 6​

Answer 1

Step-by-step explanation:

Remainder = 145

Again, we should evaluate p(5)

Let p(y) = y3 + y2 - 2y + 5

∴ p(5) = 53 + 52 - 2 x 5 + 5

= 125 + 25 - 10 + 5

= 145

Thus , we find that p(5) is the remainder when

p(y) is divided by y - 5 .
