\n" ); document.write( "Substitute,
\n" ); document.write( " $\"A=7%2BB\"$
\n" ); document.write( " $\"%287%2BB%29%5E2%2BB%5E2=289\"$
\n" ); document.write( " $\"49%2B14B%2BB%5E2%2BB%5E2=289\"$
\n" ); document.write( " $\"2B%5E2%2B14B-240=0\"$
\n" ); document.write( " $\"B%5E2%2B7B-120=0\"$
\n" ); document.write( " $\"%28B%2B15%29%28B-8%29=0\"$
\n" ); document.write( "Two solutions but only one is positive.
\n" ); document.write( " $\"B-8=0\"$
\n" ); document.write( " $\"highlight%28B=8%29\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"A-8=7\"$
\n" ); document.write( " $\"highlight%28A=15%29\"$
