For the polynomial below, 3 is a zero.
f(x) = x^3 - x^2 - 12x -18
Express f(x) as a product of linear factors
Thank you for the opportunity to help you with your question!
please check if
f(x) is correct because linear factors are not coming.
check and reply.
i will asnswer it .
if f(x) =x^3-x^2-12x+18
3 is a zero
so divide f(x) by x-3 using long division
we get f(x) = (x-3) (x^2+2x-6)
the roots of x^2+2x+6 are imaginary
and they are -1+2.2i and -1 -2.2i
x^3-x^2-12x+18 =(x-3)(x-(-1+2.2 i)) (x-(-1-2.2 i))
