\textbf{Given:}

\mathsf{x^2-y^2+3x-y+2}

\textbf{To find:}

\textsf{Factors of}

\mathsf{x^2-y^2+3x-y+2}

\textbf{Solution:}

\textsf{Consider,}

\mathsf{x^2-y^2}

\mathsf{=(x-y)(x+y)}

\mathsf{Now,}

\mathsf{x^2-y^2+3x-y+2=(x-y+l)(x+y+m)}

\textsf{Equating coefficients of x on bothsides, we get}

\mathsf{l+m=3}------(1)

\textsf{Equating coefficients of y on bothsides, we get}

\mathsf{l-m=-1}-------(2)

\mathsf{Adding\;(1)\;and\;(2)}

\mathsf{2l=2}

\implies\boxed{\mathsf{l=1}}

\mathsf{Put\;l=1\;in\;(1)}

\mathsf{1+m=3}

\mathsf{m=3-1}

\implies\boxed{\mathsf{m=2}}

\therefore\mathsf{x^2-y^2+3x-y+2=(x-y+1)(x+y+2)}
