Answer 2

Given:

We have given the equation

To Find:

Simplify the equation?

Step-by-step explanation:

• We have given the equation which is written below.

       $(2x+y)^2+(2x-y)^2$

• For simplifying the above equation we should know the formulas of the whole square of numbers. The whole square of numbers is calculated by the formulas.

       $(a+b)^2=a^2+b^2+2ab\\(a-b)^2=a^2+b^2-2ab$

• Use these formulas in the equation which is given to us.

       $(2x)^2+y^2+2(2x)(y)+(2x)^2+y^2-2(2x)(y)$

• Now simplify the brackets of the above equation.

       $4x^2+y^2+4xy+4x^2+y^2-4xy$

• Now take the like terms together and simplify them

       $4x^2+4x^2+y^2+y^2+4xy-4xy\\8x^2+2y^2$

Hence, the simplified form of given equation is $8x^2+2y^2$
