Factorise : x2 – xy + y – x(a) (x – 1) (x + y) (b) (x + 1) (x

1.	Factorise : x2 – xy + y – x(a) (x – 1) (x + y) (b) (x + 1) (x + y) (c) (x – 1) (x – y) (d) None of these
Answer» (c) (x - y)(x - 1) x² - xy + y - x = x(x - y) - 1(x - y) = (x - y)(x - 1)

Factorise : x2 – xy + y – x(a) (x – 1) (x + y) (b) (x + 1) (x + y) (c) (x – 1) (x – y) (d) None of these

Answer»

(c) (x - y)(x - 1)

x² - xy + y - x

= x(x - y) - 1(x - y)

= (x - y)(x - 1)
