Question

Write a polynomial equation of the smallest degree with roots -8, 9, 10, and -11.
Type your answer in standard form, with the equation equal to zero.

Answer 1

Roots: -8, 9, 10, and -11
So, the factors are (x+8), (x-9), (x-10) and (x+11)
And you can form an equation by the factors:
(x+8)(x-9)(x-10)(x+11) = 0
Expand the left side is what you need to do.
