Question

remainder when x3+2x2-4x+9 is divided by x-1 is explain the answer​

Answer 1

Step-by-step explanation:

The remainder theorem states that when a polynomial, f(x), is divided by a linear polynomial , x−a, the remainder of that division will be equivalent to f(a).

We have g(x)=x+1

⇒x+1=0

⇒x=−1

Remainder=p(−1)

=(−1)
