We are given polynomial function f(x)=
We are given two zeros -4 and 5.
Therefore, x=-4 and x=5 is given.
So, the two factors of the polynomial will be (x+4)(x-5).
Let us write some steps to factor the given polynomial.
Let us take above factor (x+4) first.
On factoring (x+4) we get factors
Grouping
Factoring out gcf from each group, we get
So, the final factored form of given polynomial will be
For first to factors (x+4) and (x-5) we have given roots: -4 and 5.
Let us find the root of third factor we got.
Subtracting both sides by 1.
x^2 = - 1.
On taking square root on both sides, we get a square root(-1)
+ i and -i.
Those are imaginary solutions.
Therefore, correct option is B) No, there are two imaginary solutions.
well, keeping in mind that twin sides stemming from the same "vertex" make twin angles at the "base", Check the picture below.
