Question

Xx squared - XY + x squared - xy ​

Answer 1

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:

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