Simplify the following expression completely.

(X^2 + 11x + 10)/(x^2 - x - 2)

Answer must be in binomial factor.

First, factor the numerator and denominator:

(X^2 + 11x + 10) = (X + 1)(X + 10)

(x^2 - x - 2) = (x - 2)(x + 1)

Now, cancel out the common factor of (x + 1) in the numerator and denominator:

(X + 1)(X + 10)/(x - 2)

Therefore, the simplified expression is (X + 10)/(x - 2).
