Question

Xx squared - XY + x squared - xy ​

Answer 1

Answer and Step-by-step explanation:

`x^(2) - xy + x^(2) -xy\\\\2x^(2) -2xy`

This is the answer.

Answer 2

In case your expression is:

`x^2\:-\:xy\:+\:x^2\:-\:xy`

Solution:

Given the expression

`x^2\:-\:xy\:+\:x^2\:-\:xy`

Group like terms

`x^2\:-\:xy\:+\:x^2\:-\:xy=x^2+x^2-xy-xy`

Add similar elements: x²+x² = 2x²

`=2x^2-xy-xy`

Add similar elements: -xy-xy = -2xy

`=2x^2-2xy`

Thus,

`x^2-xy+x^2-xy=2x^2-2xy`

In case your expression is:

`\left(xx\right)^2\:-\:xy\:+\:x^2\:-\:xy`

Solution:

Given the expression

`\left(xx\right)^2\:-\:xy\:+\:x^2\:-\:xy`

Group like terms

`\left(xx\right)^2\:-\:xy\:+\:x^2\:-\:xy=x^2-xy-xy+\left(xx\right)^2`

Add similar elements: -xy-xy = -2xy

`=x^2-2xy+\left(xx\right)^2`

as (xx)² = x⁴

so
`=x^2-2xy+x^4`

Therefore, we conclude that:

• 
  `\left(xx\right)^2\:-\:xy\:+\:x^2\:-\:xy=x^2-2xy+x^4`
