$(m+3)/(m+2); m \ne -4, -2$
In order to simplify this expression, we need something to be in the numerator and the denominator of the fraction so it can be canceled out. Therefore, we factor and obtain: $(m+4)(m+3)/(m+2)(m+4) \\\\ (m+3)/(m+2)$ m cannot equal -2 or -4, for if this were the case, the denominator of the fraction would cancel out to 0, which is not allowed.
