Question

proved that (x+y) (x+y) =x•x +2xy + y•y​

Answer 1

To Prove:

_____________

(x+y) (x+y) =x•x+2xy+y•y

Proof:

_______

Taking L. H. S,

(x+y) (x+y)

→ x(x+y) +y(x+y)

→ x•x+xy+yx+y•y

→x•x+2xy+y•y=R.H.S

Hence, It is proved that (x+y) (x+y) =x•x+2xy+y•y

Answer 2

To Prove:

_____________

(x+y) (x+y) =x•x+2xy+y•y

Proof:

_______

Taking L. H. S,

(x+y) (x+y)

→ x(x+y) +y(x+y)

→ x•x+xy+yx+y•y

→x•x+2xy+y•y=R.H.S

Hence, It is proved that (x+y) (x+y) =x•x+2xy+y•y
