Question 206945
(4x-3y(squared))squared
-----
i think what you are asking is (4x-3y^2)^2 which looks like {{{(4x-3y^2)^2}}}
-----
this is equivalent to (4x-3y^2)*(4x-3y^2) which looks like {{{(4x-3y^2)*(4x-3y^2)}}}
-----
breaking this down yields the following:
-----
(-3y^2) * (-3y^2) = 9y^4 which looks like {{{(-3y^2) * (-3y^2) = 9y^4}}}
-----
(-3y^2) * (4x) = -12x*y^2 which looks like {{{(-3y^2) * (4x) = -12x*y^2}}}
-----
(4x) * (-3y^2) = -12x*y^2 which looks like  {{{(4x) * (-3y^2) = -12x*y^2}}}
-----
(4x) * (4x) = 16x^2 which looks like {{{(4x) * (4x) = 16x^2}}}
-----
if you add all these piece parts together, then our answer is:
16x^2 - 24xy^2 + 9y^4 which looks like {{{16x^2 - 24xy^2 + 9y^4}}}
