\"x%5E4+-+10x%5E2+%2B+9\"seperate and group them
\n" ); document.write( "\"%28x%5E4+-+x%5E2%29%2B%28-9x%5E2+%2B+9%29\" factor out what is needed x^2 and -9
\n" ); document.write( "\"x%5E2%28x%5E2+-+1%29%2B%28-9%29%28x%5E2+-+1%29\" factor out x^2-1
\n" ); document.write( "\"%28x%5E2-1%29%28x%5E2-9%29\" these are perfect squares factor them to below
\n" ); document.write( "\"%28x-1%29%28x%2B1%29%28x-3%29%28x%2B3%29\" set = to 0 to solve for x
\n" ); document.write( "x=1,-1,3,-3
\n" ); document.write( "
