Question 947450

exsponets(^1) pretend 

what is the factored form of 
9x^4-6x^3+18x^2-12x

i think its 3x(3x^4-2x) but not sure can you help?
<pre>Not even close!! Sorry!! 
{{{9x^4 - 6x^3 + 18x^2 - 12x}}}
{{{3x(3x^3 - 2x^2 + 6x - 4)}}} ------ Factoring out GCF, 3x
3x(<b><u>3x^3 - 2x^2</b></u>  <b><u>+ 6x - 4</b></u>)
{{{3x(x^2(3x - 2) + 2(3x - 2))}}} ------ Factoring out GCF in pairs
{{{highlight_green(3x(x^2 + 2)(3x - 2))}}}
