remainder = - 1

6x² + 11x - 3 ÷ (x + 2 ) = 6x - 1 -
(1)/(x+2)

Answer: The required remainder is 1.

Step-by-step explanation: We are given to find the remainder when the following polynomial is divided by (x + 2) :


p(x)=6x^2+11x-3.

Remainder Theorem : If a polynomial f(x) is divided by (x - a), then the remainder is f(a).

So, for the given polynomial p(x), the remainder will be equal to p(-2).

We have


p(-2)\\\\=6(-2)^2+11(-2)-3\\\\=24-22-3\\\\=-1.

Thus, the required remainder is -1.
