Question

Factorise x^2+y-xy-x

Answer 1

X^2 - XY + Y - X
X(X-Y) - 1(X-Y)
(X-Y)(X-1)

Answer 2

$\textbf{ Hello Mate! }$

${x}^{2} + y - xy - x \\ \\ {x}^{2} - xy - x + y \\ \\x (x - y) - 1(x - y) \\ \\ (x - 1)(x - y)$

$\boxed{ \textsf{ Factors\:are\:(\:x\:-\:1\:)(\:x\:-\:y\:) }}$

Have great future ahead!
