The quadratic eqn system $\"ax%5E2%2Bbx%2Bc=0\"$ is calculated using this formula:
\n" ); document.write( " $\"x=%28-b%2B-sqrt%28b%5E2-4%2Aa%2Ac%29%29%2F%282%2Aa%29\"$ \r
\n" ); document.write( "\n" ); document.write( "Simplifying the eqn gives: $\"x%5E2%2B10x%2B25=8\"$
\n" ); document.write( " $\"x%5E2%2B10x%2B25-8=0\"$
\n" ); document.write( "Therefore $\"x%5E2%2B10x%2B17=0\"$ into the formula: $\"x=%28-10%2B-sqrt%2810%5E2-4%2A1%2A17%29%29%2F%282%2A1%29\"$
\n" ); document.write( "Hence $\"x=-7.83\"$ and $\"x=-2.17\"$ \n" ); document.write( "
