square root of -6 and -42.
\n" ); document.write( "Both numbers are next to each other with the square root sign in front of each number.
\n" ); document.write( ":
\n" ); document.write( " $\"sqrt%28-6%29+%2A+sqrt%28-42%29\"$
\n" ); document.write( "extract the square root of -1; i; multiply the values
\n" ); document.write( " $\"i%2Asqrt%286%29+%2A+i%2Asqrt%2842%29\"$ = $\"i%5E2%2Asqrt%286%2A42%29\"$ = $\"-1%2Asqrt%28252%29\"$
\n" ); document.write( "Factor to reveal a perfect square
\n" ); document.write( " $\"-1%2Asqrt%2836%2A7%29\"$
