Answer:
Step-by-step explanation:
Given that zeroes of a polynomial are
-3, -1, 1, 4
Degree of the polynomial is 4
Also leading coefficient is 1.
So we find easily the polynomial
Since polynomial is 0 at the given four points the polynomial is a product of
[tex](x+3)(x+1)(x-1)(x-4)\\=(x^2-1)(x^2-x-12)\\= (x^4-x^3-13x^2+x+12)[/tex]
Since leading coefficient is given to be 1 we need not multiply an arbitrary constant a
so the required polynomial is
[tex](x^4-x^3-13x^2+x+12)[/tex]
