Is the binomial a factor of the polynomial function? f(x)=x3+3x2−16x−48
1 answer:
Answer:
(x−3) no
(x+2) no
(x−4) yes
Step-by-step explanation:
Plug in the root of each binomial to see if it is also a root of f(x).
f(3) = -42
f(-2) = -12
f(4) = 0
Of the choices available, only (x−4) is a factor of f(x).
