Question
Factorize: $x^2 + y - xy - x$
✓
Answer
$x^2 + y - xy - x$ On rearranging $x^2 - xy - x + y$
Taking $x$ common in the $(x^2 - xy)$ and $-1$ in $(-x + y) = x(x - y) - 1(x - y)$
Taking $(x - y)$ common in the terms $= (x - y)(x - 1)$
$\therefore$ $x^2 + y - xy - x = (x - y)(x - 1)$
Taking $x$ common in the $(x^2 - xy)$ and $-1$ in $(-x + y) = x(x - y) - 1(x - y)$
Taking $(x - y)$ common in the terms $= (x - y)(x - 1)$
$\therefore$ $x^2 + y - xy - x = (x - y)(x - 1)$
