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