$\"10x%5E2=9x%2B9\"$ , EQN 1
\n" ); document.write( " $\"10x%5E2-9x-9=0\"$ -------> it follows quadratic eqn: $\"ax%5E2%2Bbx%2Bc=0\"$
\n" ); document.write( "where----> $\"system%28a=10%2Cb=-9%2Cc=-9%29\"$
\n" ); document.write( "Plug in the values to quadratic eqn:
\n" ); document.write( " $\"x=%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F%282a%29\"$
\n" ); document.write( "ANSWERS:
\n" ); document.write( " $\"highlight%28x=3%2F2%29\"$ ; $\"highlight%28x=-3%2F5%29\"$
\n" ); document.write( "Check via EQN 1;
\n" ); document.write( " $\"10%283%2F2%29%5E2=9%283%2F2%29%2B9\"$
\n" ); document.write( " $\"10%289%2F4%29=%2827%2F2%29%2B9\"$
\n" ); document.write( " $\"90%2F4=%2827%2B18%29%2F2\"$
