Answer:
f(x) = (x+4)(x-1)(x-2)
Step-by-step explanation:
We are given the roots as -4, 1, and 2
We are also given the leading coefficient as 1
We can write the polynomial as
f(x)= a( x- r1)(x-r2) (x-r3) ...... where rn are the roots and a is the leading coefficient
f(x)= 1( x- -4) (x-1)(x-2)
= 1(x+4) (x-1) (x-2)
We can drop the leading 1 since it is not needed
f(x) = (x+4)(x-1)(x-2)
