Answer 1

\[\frac{ -5x-10 }{ x^2+3_{x}+2}\]

Answer 2

\[\frac{ -5x-10 }{ x ^{2}+3x+2 }=\frac{ -5\left( x+2 \right) }{ x ^{2}+2x+x+2 }\]
\[=\frac{ -5\left( x+2 \right) }{ x \left( x+2 \right)+1\left( x+2 \right) }\]
\[=\frac{ -5\left( x+2 \right) }{\left( x+2 \right)\left( x+1 \right) }=\frac{ -5 }{ x+1 }\]
