​

Answer 1

ANSWER-

Step-by-step explanation:

$(1)( {x + y })^{2} = {x}^{2} + {y}^{2} + 2xy \\ (2) {x}^{2} - {y}^{2} = (x + y)(x - y) \\ (3) {x}^{2} + {y}^{2} = ({x + y})^{2} - 2xy$

Answer 2

ANSWER-

Step-by-step explanation:

$(1) {x}^{2} + {y}^{2} + 2xy \\ (2)(x + y)(x - y) \\ (3) ({x + y})^{2} - 2xy$
