You can put this solution on YOUR website!
i have looked on the web and not found much at all, however one pdf had an example where it multiplied by a \"surd conjugate\". Looking into this, it looks like \"x%2Bsqrt%28y%29\" has the conjugate \"x-sqrt%28y%29\". As for why...that is the definition of the conjugate. Simple as that.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "As for the reason behind using a conjugate...it removes any irrational/surd parts, since \"%28x%2Bsqrt%28y%29%29%28x%2Bsqrt%28y%29%29\" is \"x%5E2+-+x%2Asqrt%28y%29+%2B+x%2Asqrt%28y%29+-+y\" --> \"x%5E2+-+y\".\r
