For the polynomial below, the -2 is a zero.
f(x)= x^3 - 2x^2 - 6x + 4
Express f(x) as a product of linear factors.
Use fractions or radicals in answers not decimals.
Thank you for the opportunity to help you with your question!
since -2 is a zero,so, x -(-2) =0 x +2 = 0therefore,f(x)= x^3 - 2x^2 - 6x + 4
= x^2(x+2) - 4x(x+2) +2(x+2)=(x^2 -4x+2)(x+2) (Answer)
