Question:

Consider a polynomial f(x)=x^3+2x^2-5x-6. Determine whether (x+1) is a factor of f (x).

Nikhil J.

Answer:

By the Factor theorem, (x + 1) is a factor of f (x) if f (–1) = 0. Obtain the value of f (–1). f(-1)=(-1)^3+2(-1)^2-5(-1)-6= -1+2+5-6 Since f (–1) = 0, (x + 1) is a factor of f (x).
