I need help with COMPLETELY factoring out the polynomial $\"3x%5E3-12x\"$
\n" ); document.write( "Ok first step would be to factor out $\"3x\"$ which leaves us with
\n" ); document.write( " $\"3x%28x%5E2-4%29\"$ Now we can use the differance of squares formula which says that $\"a%5E2-b%5E2=%28a-b%29%28a%2Bb%29\"$
\n" ); document.write( "For us $\"a=x\"$ and $\"b=-2\"$
\n" ); document.write( "This gives us $\"3x%28x%5E2-4%29=3x%28x%2B2%29%28x-2%29\"$ we factored the $\"x%5E2-4\"$ using difference of squares. \n" ); document.write( "
