Answer 2

Answer:

$y=\frac{-5}{2} , y=-2$

Step-by-step explanation:

Given : $2y^{2} +9y+10=0$

To Find: Solve the equation .

Solution :

$2y^{2} +9y+10=0$

$2y^{2} +4y+5y+10=0$

$2y(y+2)+5(y+2)=0$

$(2y+5)(y+2)=0$

$2y+5=0 , y+2=0$

$y=\frac{-5}{2} , y=-2$

Thus y = -2.5 , -2

Hence the solution of $2y^{2} +9y+10=0$ is -2.5,2
