Hello mate.

Thanks for asking this useful question

So\:your\:answer\:is=>

Our given equation is =>


=> \boxed {\frac{3y}{y^{2}+7y+10}+ \frac{2}{y+2}}


Let our final summation be "x"


=> \boxed { \frac{3y}{y^{2}+7y+10}+ \frac{2}{y+2}\:=\:x}


taking LCM on LHS ,


=> \frac {3y(y+2)+2(y^{2}+7y+10)}{(y+2)(y^{2}+7y+10 )}\:=\:x


=> \frac{3y^{2}+6y+2y^{2}+14y+20}{(y+2)(y^{2}+7y+10)}\:=\:x


By solving and using factorisation method on denominator side ;


=> \frac {5y^{2}+20y+20}{(y+2)[(y+2)(y+5)]}\:=\:x


=> \frac{5(y^{2}+4y+4)}{(y+2)(y+2)(y+5)}\:=\:x


by using factorisation method on nominator side ,


=> \frac {5[(y+2)(y+2)]}{(y+2)(y+2)(y+5)}\:=\:x


 =>\frac {5( {\cancel {(y+2) (y+2)})}}{ {\cancel {(y+2) (y+2)}} (y+5)}\:=\:x


 =>\boxed { \frac{5}{y+5}\:=\:x}


So our final equation is ,


 \boxed {\frac {3y}{y^{2}+7y+10}+ \frac {2}{y+2} \:=\: \frac {5}{y+5}}



Hope u understood ^_^
