If f is a polynomial function and xminus−5 is a factor of f, then f(5)equals=

if (x - 5 ) is a factor of f(x ) then x = 5 is a root of f(x) and f(5) = 0

Step-by-step explanation:

A function can be simplified by it's roots.

For example, a second order function expressed by the following equation:

Can be expressed in function of it's roots such that .

Is is a factor of f, this means that f can be expressed in function of , that is, x = 5 is a root of the equation.

This means that:

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

i am only able to answer the first part. i am not sure about the second part. sorry
