Question

(

(b)

Given x and y are two numbers. If we add the twice of the square of half the sum of the numbers to the twice of the square of half of their difference, then find the algebraic expression.​

Answer 1

Answer:

according to sentence,

2(x+y)^2/2+2(x-y)^2/2=0

here 2 gets cancelled and ,

(x+y)^2+(x-y)^2=0

x^2+y^2+2xy+x^2+y^2-2xy=0

here -2xy and +2xy gets cancelled

2x^2+2y^2=0

now take 2 as common then,

2(x^2+y^2)=0

x^2+y^2=0 is the algebraic expression

Answer 2
