Question

Factorise the following. xsquare+y-xy-x

Answer 1

Step-by-step explanation:

We consider,

x square + y-xy-x = 0

x square - xy -x + y = 0

x(x-y) -1(x-y) =0

(x-y) (x-1) =0

(x-y) = 0 or. (x-1)= 0

x = y or x = 1

then, also

y = 1

Verification :

(1) (1) + (1) - (1)(1) -1=0

1 + 1 -1 -1 = 0

2 - 2 = 0.
