Hello!
\n" ); document.write( "In order to rationalize the denominator, we need to make use of the following rule:\r
\n" ); document.write( "\n" ); document.write( "\"%28a%2Bb%29%28a-b%29=a%5E2-b%5E2\"\r
\n" ); document.write( "\n" ); document.write( "The denominator in your case is \"3-+sqrt%286%29\" so in order to eliminate the square root (\"rationalize it\"), we can multiply it by \"3%2Bsqrt%286%29\". Of course, we must multiply the numerator too by that number. So we have:\r
\n" ); document.write( "\n" ); document.write( "\r
\n" ); document.write( "\n" ); document.write( "So your expression becomes:\r
\n" ); document.write( "\n" ); document.write( "\"+%28sqrt%287%29%283%2Bsqrt%286%29%29%29%2F+%289+-+6%29\"
\n" ); document.write( "\"+%28sqrt%287%29%283%2Bsqrt%286%29%29%29%2F3\"\r
\n" ); document.write( "\n" ); document.write( "So now we've rationalized the denominator.\r
\n" ); document.write( "
