You can put this solution on YOUR website!
let y = the unknown number
\n" ); document.write( ":
\n" ); document.write( " $\"%282x%29%2F%282x-3%29\"$ = $\"y%2F%288x%5E3-27%29\"$
\n" ); document.write( "multiply both sides by (8x^3-27)
\n" ); document.write( "y = $\"%282x%288x%5E3-27%29%29%2F%282x-3%29%29\"$
\n" ); document.write( "we can factor
\n" ); document.write( "y = $\"%282x%282x-3%29%284x%5E2%2B6x%2B9%29%29%2F%282x-3%29%29\"$
\n" ); document.write( "Cancel
\n" ); document.write( "y = $\"2x%284x%5E2%2B6x%2B9%29%29\"$
