Question 34069
you cannot solve it since it isn't an equation...no equals sign.


You can multiply out the brackets if you wanted to:
{{{ (x^2 + 2y)(x^2 - 2y) }}}
{{{ x^2*x^2 - 2x^2y + 2x^2y - 2y*2y }}}
{{{ x^4 - 4y^2 }}}


This is just a simpler version of what you started with...not a solution ie no "x equals..."
