Question

how can you prove that
$(x + y {)}^{2} = {x}^{2} + {y}^{2} + 2xy$
​

Answer 1

Step-by-step explanation:

$\huge\mathfrak{\underline{\underline{\red{Answer:-}}}}$

$it \: is \: the \: property$

${(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab$

$ie \: {(x + y})^{2} = {x}^{2} + {y}^{2} + 2xy$

Answer 2

HERE IS UR ANSWER DEAR,

LHS :

= ( x+y)²

= (x+y)(x+y)

= x² + xy +xy + y²

= x² + 2xy +y²

= RHS

hence proved !!!!
