Hi,

I've got an to assignment, to reduce/expand the following work:

(x^{3}+ √12)^{2}+ √4 * 12^{(1/2)}* (x^{2a + 3}/ x^{2a})

I've tried to reduce it in pieces.

(x^{3}+ √12)^{2}= x^{6}- 4√3x^{3 }√4 * 12^{(1/2)}* (x^{2a + 3}/ x^{2a}) = 12 + 4√3x^{3}

So in all, is it equal to:

x^{6}+ 4√3x^{3 }+ 12 + 4√3x^{3 Which is equal to: }x^{6} + 8√3x^{3 }+ 12

Though, i'm not sure, that I'm doing it the right way, or if there is more I can do, than the following.

Thanks in advance.
