Question

Factorise
a(a-2) - b(b-2)

Answer 1

Answer:

Step-by-step explanation:

if we expand the brackets we get

a.a- 2.a-b.b-2.b

consider a.a -b.b we can factorize that as

(a-b)(a+b)

and now take 2 common in remaining two terms we get

2(a-b)

now finaly we get

(a-b)(a+b)+2(a-b)

now take (a-b) as common

we get (a-b)(2+a+b)
