Solve. \\ y''+y'+\frac{y}{4}=1+xe^x when y(0)=0, \ \ y'(0)=1

Question:

Solve.

{eq}y''+y'+\frac{y}{4}=1+xe^x{/eq} when {eq}y(0)=0, \ \ y'(0)=1{/eq}

Differential Equation:

Differential equation of form {eq}\displaystyle \phi \left(D\right)y=f\left(x\right)\:where,\:D=\frac{d}{dx} {/eq} has solution {eq}\displaystyle y=y_c+y_p {/eq}

Where, complimentary function {eq}\displaystyle y_c {/eq} is depend on auxiliary equation and

particular integral {eq}\displaystyle y_p {/eq} is depend on function f(x).

Use the initial conditions to find the value of constants.
