Two numbers I'm assuming?
\n" ); document.write( " $\"AB=-30\"$
\n" ); document.write( " $\"A%2BB=-34\"$
\n" ); document.write( "From the first,
\n" ); document.write( " $\"A=-30%2FB\"$
\n" ); document.write( "Substitute into the second,
\n" ); document.write( " $\"-30%2FB%2BB=-34\"$
\n" ); document.write( " $\"-30%2BB%5E2=-34B\"$
\n" ); document.write( " $\"B%5E2%2B34B-30=0\"$
\n" ); document.write( " $\"%28B%5E2%2B34B%2B289%29-30=289\"$
\n" ); document.write( " $\"%28B%2B17%29%5E2=319\"$
\n" ); document.write( " $\"B%2B17=0+%2B-+sqrt%28319%29\"$
\n" ); document.write( " $\"B=-17+%2B-+sqrt%28319%29\"$
\n" ); document.write( "Now for each B solve for A.
\n" ); document.write( " $\"B=-17%2Bsqrt%28319%29\"$
\n" ); document.write( " $\"A-17%2Bsqrt%28319%29=-34\"$
\n" ); document.write( " $\"A=-17-sqrt%28319%29\"$
\n" ); document.write( "and
\n" ); document.write( " $\"B=-17-sqrt%28319%29\"$
\n" ); document.write( " $\"A-17-sqrt%28319%29=-34\"$
\n" ); document.write( " $\"A=17%2Bsqrt%28319%29\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
