Question

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

Answer 1

Answer:

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

(a-b)²-(a²-b²)

a²+b²-2ab-a²+b²

2b²-2ab

2b(b-a)

this is your answer ❣️❣️✌️✌️

Answer 2

${\bold {\boxed{\underline {\huge {\red {Answer :}}}}}}$

$(x - y)(x - y) - (x + y)(x - y)$

${(x - y)}^{2} -( {x}^{2} - {y}^{2})$

${x}^{2} + {y}^{2} - 2xy - {x}^{2} + {y}^{2}$

$2 {y}^{2} - 2xy \\ 2y(y - x)$
