Question

factorise ab+bx-ay-by

Answer 1

Answer:

Step-by-step explanation:

ab+bx-ay-by

b(a+x)-y(a+b)

(b-y)(a+x)(a+b)

Answer 2

Given  :

ab + bx - ay - by

The question is incorrect ^^"

The question would be :

ax + bx - ay - by

Take x as common in the first 2 terms

= > x ( a + b ) - ay - by

Take y as common in the last 2 terms

= > x ( a + b ) - y ( a + b )

= > ( a + b )( x - y )

The answer is ( a + b )( x - y )
