a(a-3)-b(b-3)
a² - 3a - b² - 3b
a² - b² - 3a - 3b
(a+b)(a-b) - 3(a+b) [since a²-b² = (a+b)(a-b)]
Let (a+b) = x
therefore
x(a-b) - 3x
x (a-b-3)
(a+b) (a-b-3) is the answer [since x = a+b]
a² - 3a - b² - 3b
a² - b² - 3a - 3b
(a+b)(a-b) - 3(a+b) [since a²-b² = (a+b)(a-b)]
Let (a+b) = x
therefore
x(a-b) - 3x
x (a-b-3)
(a+b) (a-b-3) is the answer [since x = a+b]
