Question 1086508
{{{ x^2 + 2x*( x-y ) + ( x-y )^2 }}}
Rewrite it in the reverse direction
{{{ ( x-y )^2 + 2x*( x-y ) + x^2 }}}
{{{ ( ( x-y ) + x )^2 }}}
or, reducing further:
{{{ ( 2x - y )^2 }}}
------------------------------
I'll do a rough check.
suppose {{{ x = 11 }}} and {{{ y = 7 }}}
{{{ x^2 + 2x*( x-y ) + ( x-y )^2 }}}
{{{ 11^2 + 2*11*4 + 4^2 }}}
{{{ 121 + 88 + 16 }}}
{{{ 225 }}}
----------------------------------
And the solution:
{{{ ( 2x - y )^2 }}}
{{{ ( 2*11 - 7 )^2 }}}
{{{ ( 22 - 7 )^2 }}}
{{{ 15^2 }}}
{{{ 225 }}}
I could be right
