11-109.

Multiple Choice: Which differential equation below is a solution to $\frac { d y } { d x }= y^2(2t + 3)$?

1. $y = −\frac { 1 } { t ^ { 2 } + 3 t + 2 }$

1. $y =\frac { 1 } { t ^ { 2 } + 3 t + 2 }$

1. $y = e^{−(t^2+3t+2)}$

1. $y = e^{t^2+3t+2}$

1. None of these.

$\int\frac{dy}{y^2}=\int(2t+3)dt$
