Question

factorize the following (x+y) -(x+y) 2
​

Answer 1

The factorisation of 1 + xy - x - y is equal to "(1 - x)(1 - y)".

Step-by-step explanation:

We have,

1 + xy - x - y

To find, the factorisation of 1 + xy - x - y = ?

∴ 1 + xy - x - y

= 1 - x - y + xy

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

= (1 - x)(1 - y)

∴ The factorisation of 1 + xy - x - y =  (1 - x)(1 - y)

Thus, the factorisation of 1 + xy - x - y is equal to "(1 - x)(1 - y)".
