Ordinary Differential Equations/Exact 3

$\begin{array}{cc}& \text{Question 1:}\\ & \text{Consider the following equation}:\\ & \frac{dy}{dx}+2y=x^2{e}^{-2x}+5\\ \end{array}$

$\text{find the general solution of the above equation}$

hint: using the following: $y=\frac{\int e^{\int P\left(x\right)dx}Q\left(x\right)dx+C}{e^{\int P\left(x\right)dx}}$ Template:BookCat
