2 a^{2}+5 a+3

2 a^{2}+3 a+2 a+3

2 a^{2}+3 a+2 a+3

(2 a+3)(a+1)  

a^{2}+6 a+5

(a+1)(a+5)

2 a^{2}+7 a+6

2 a^{2}+4 a+3 a+6

\begin{aligned}&2 a(a+2)+3(a+2)\\&(2 a+3)(a+2)\\&-5 a^{2}-35 a-50\\&\Rightarrow-5\left[a^{2}+7 a+10\right]\\&\Rightarrow-5[a+5][a+2]\end{aligned}

\frac{2 a^{2}-5 a+3}{2 a^{2}+7 a+6} \div \frac{a^{2}+6 a+5}{-5 a^{2}-35 a-50}

\begin{aligned}&\begin{array}{l}\Rightarrow \frac{(2 a+3)(a+1)}{(2 a+3)(a+2)}+\frac{(a+1)(a+5)}{-5(a+5)(a+2)} \\\Rightarrow \frac{(2 a+3)(a+1)}{(2 a+3)(a+2)} \times \frac{-5(a+5)(a+2)}{(a+1)(a+5)} \\\Rightarrow-5\end{array}\end{aligned}
