Text Solution

Verified by Experts

Give that, `(dy)/(dx)+2xy=y` ltbr `Rightarrow(dy)/(dx)+2xy-y=0`
`Rightarrow(dy)/(dx)+(2x-1)y=0`
Which is linear differential equation.
On comparing it with `(dy)/(dx)+Py=Q`, we get
`P=(2x-1),Q=0`
`IF=e^(intPdx)=e^(int(2x-1))dx`
`=e((2x^(2))/(2)-x)=e^(x^(2)-x)`
The complete solution is
`y.e^(x^(2)-x)=intQ.e^(x^(2)-x)dx+C`
`Rightarrow y.e^(x^(2-x))=0+C`
`Rightarrow y=C e^(x-x^(2))`
