Answer

$\dfrac{4}{x+3}-2=-\dfrac{2(x+1)}{x+3}$

Work Step by Step

$\dfrac{4}{x+3}-2$ Evaluate the substraction and simplify if possible: $\dfrac{4}{x+3}-2=\dfrac{4-2(x+3)}{x+3}=\dfrac{4-2x-6}{x+3}=...$ $...=\dfrac{-2x-2}{x+3}=...$ Take out common factor $-2$ to provide a more simplified answer: $...=-\dfrac{2(x+1)}{x+3}$
