Problema Solution
Form a polynomial with degree 4 and zeros at -4, -7, 2 and 5
Answer provided by our tutors
if -4, -7, 2 and 5 are zeros
then (x+4), (x+7), (x-2) and (x-5) are factors of the polynomial
thenthe polynomial required is
p(x)=(x+4)(x+7)(x-2)(x-5)
=x4 +4x3-39x2 -86x+280
hence the result.
