What Is The Remainder When B, Is Divided By ,

What is the remainder when

is divided by

 

Answer:

-5

Step-by-step explanation:

By remainder theorem , substitute the root of the binomial to the polynomial. And the excess from 0 will be the remainder

Root of b-2 is 2

Substitute it to the polynomial

Remainder = b²+3b-15

R(x) = 2²+3(2)-15

R(x) = 4+6-15

R(x) = 10-15

R(x) = -5

Therefore , the remainder is -5
