Question

anonymous · Answer

$$(6x-5)^3(2)(x^2+4)(2x)+(x^2+4)^2(3)(6x-5)^2(6))$$

anonymous · Answer

I got $$7200-19280 x+21168 x^2-17780 x^3+10890 x^4-3240 x^5+1512 x^6$$

I understand how to expand it but not how to simplify it

pfenn1 · Answer

I think that is all you can do.  You could take a 2 out of all the integers but that doesn't really simplify it at all.

anonymous · Answer

$$2x(x^2+4)(6x-5)\left[ (6x-5)^2+9(x^2+4) \right]$$

anonymous · Answer

Sorry, the final answer should be $$2 (5-6x)^2 (4+x^2) (36+x (-10+21x))$$ but I don't know how they get it...

Wow.  I have no idea how to get to there.  It would take me quite a while to get that.  I got that first 2....but the rest. Whew!
