If \"A\" and \"B\" are two binomials which add to a third binomial \"C\", then this means that \"A%2BB=C\". If we know what \"A\" and \"C\" are, then we can subtract \"A\" from both sides to solve for \"B\" like so:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"B=C-A\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So in this case, \"C=3x%5E2-5x\", \"A=2x%5E2-x\", and \"B\" is our unknown binomial\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"B=C-A\" Start with the given equation.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"B=%283x%5E2-5x%29-%282x%5E2-x%29\" Plug in \"C=3x%5E2-5x\" and \"A=2x%5E2-x\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"B=3x%5E2-5x-2x%5E2%2Bx\" Distribute\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"B=x%5E2-4x\" Combine like terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the unknown binomial is \"x%5E2-4x\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
