Question

Factor the term ab - by - ay + y2

Answer 1

`\boxed{(a-y) (b - y)}`

Explanation:

Rearrange the terms.

`(ab - ay) (-by + y^2)`

Factor out common term.

`a (b - y) -y ( b - y)`

Apply rule :
`a(b+c)+d(b + c) = (a+d)(b+c)`

`a (b +- y) +-y ( b +- y)`

`(a+-y) (b +- y)`

Answer 2

(a - y) (b - y)

Explanation:

(ab - ay) (-by + y^2)

a (b - y) -y ( b - y)

(a-y) (b - y)
