Discussion Problems Suppose the solution of the boundary-value problem \(y^{\prime \prime}+P y^{\prime}+Q y=f(x)\), y(a)=0, y(b)=0, a<b, is given by \(y_{p}(x)=\int_{a}^{b} G(x, t) f(t) d t\) where \(y_{1}(x)\) and \(y_{2}(x)\) are solutions of the associated homogeneous differential equation chosen in the construction of G(x, t) so that \(y_{1}(a)=0\) and \(y_{2}(b)=0\). Prove that the solution of the boundary-value problem with nonhomogeneous DE and boundary conditions, \(y^{\prime \prime}+P y^{\prime}+Q y=f(x)\), y(a)=A, y(b)=B is given by \(y(x)=y_{p}(x)+\frac{B}{y_{1}(b)} y_{1}(x)+\frac{A}{y_{2}(a)} y_{2}(x)\) [Hint: In your proof, you will have to show that \(y_{1}(b) \neq 0\) and \(y_{2}(a) \neq 0\). Reread the assumptions following (23).]
