The first step for solving this expression is to factor out 4 from the numerator (top) of the question.
[tex] \frac{4(x-2)}{4x+20} [/tex]
Factor out 4 from the denominator (bottom) of the fraction.
[tex] \frac{4(x-2)}{4(x+5)} [/tex]
Lastly,, reduce the fraction with 4 once more to get your final answer.
[tex] \frac{x-2}{x+5} [/tex]
