Problema Solution

Write a polynomial of the lowest degree with zeros of -4( multiplicity 1), 1 (multiplicity 1) with f(0)=16

Answer provided by our tutors

f(x) = a(x - (-4))(x - 1)

We use the fact that f(0) = 16 to find a:

a(0 - (-4))(0 - 1) = 16

-4a = 16

a = -16/4

a = -4

The polynomial is:

f(x) = (-4)(x - (-4))(x - 1)

f(x) = -4x^2 - 12x + 16
