Question

p(X)=3x^3+2x^2-4x+1 find p(-1) p(0) p(-1/2​

Answer 1

Answer:

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)

3

−2(−1)

2

−4(−1)−1

=−1−2+4−1

=0
