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
