Question #N363
The expression $\frac{x^2 + 5x + 6}{x + 2}$ is equivalent to which of the following, when $x \neq -2$?
A. x + 3
B. x + 6
C. x^2 + 3
D. x^2 + 6
Correct Answer is: A
The numerator can be factored as $(x+2)(x+3)$, so the expression becomes $\frac{(x+2)(x+3)}{x+2}$. Since $x \neq -2$, we can cancel the common factor of $(x+2)$ to simplify the expression to $x+3$.
