$\"y%5E2=100-x%5E2\"$
\n" ); document.write( " $\"y=%282%2Bx%29\"$
\n" ); document.write( "Substitute (2+x)\r
\n" ); document.write( "\n" ); document.write( " $\"%282%2Bx%29%5E2=100-x%5E2\"$
\n" ); document.write( " $\"4%2B4x%2Bx%5E2=100-x%5E2\"$
\n" ); document.write( " $\"2x%5E2%2B4x-96=0\"$
\n" ); document.write( "Divide by 2
\n" ); document.write( " $\"x%5E2%2B2x-48=0\"$
\n" ); document.write( " $\"x=6\"$
\n" ); document.write( " $\"x=-8\"$
\n" ); document.write( " $\"y=2%2B6=8\"$
\n" ); document.write( " $\"y=2%2B%28-8%29=-6\"$
\n" ); document.write( "Ans:(6,8) and (-8,-6)\r
