Question

x square-y square-2y-1 square

Answer 1

x2−(y2+2y+1)x2−(y2+2y+1) ==>we take - commonx2−(y+1)2==>(a2+2ab+b2)=(a+b)2x2−(y+1)2==>(a2+2ab+b2)=(a+b)2(x−(y+1))(x+(y+1))(x−(y+1))(x+(y+1)) =>applying the main rule a2−b2=(a−b)(a+b)a2−b2=(a−b)(a+b)(x−y−1)(x+y+1)(x−y−1)(x+y+1) =>simplyfying the answer
