Given:
The given polynomial is:
To find the roots of the given polynomial.
To find the roots we have to take
So,
Formula
By quadratic formula, the root of the equation is,
and
Now,
Putting, we get,
and
and
Hence,
The values of the roots of the given polynomial are and
Hence, Option A and F are the correct answer.
The formula we need is this one: 
. Filling in accordingly, we have x+4(x+4+1)=x+1(x+1+11). Simplifying that we get (x+4)(x+5)=(x+1)(x+12). We will FOIL both sides to get 
. Combining like terms gives us this simplification: 0=4x-8. If we factor out the common 4, we have 0 = 4(x-2). By the Zero Product Property, eitheer 4=0 or x-2=0. Well obviously, 4 does not equal zero, so x-2 = 0, and x = 2.
