you need to put this in synthetic division
take the coef from power of greatest to least
1 2 -109 -110 and use factors of -110 to try
-1 works so (X+1) is a factor of equation
rewrite: (x+1)(X^2+X-110)
find root of (X^2+X-110) COME TO be -11,10
so factor form is (X+11)(X-10)(X+1)
n find the roots
find the zeros of the function:
f(x)=x^3+2x^2-109x-110
I think I need to factor but everytime I do, it doesn't look right.
