Substitute,
\n" ); document.write( " $\"x%5E2%2B4%28x%2B5%29%2B2x=11\"$
\n" ); document.write( " $\"x%5E2%2B4x%2B20%2B2x-11=0\"$
\n" ); document.write( " $\"x%5E2%2B6x%2B9=0\"$
\n" ); document.write( " $\"%28x%2B3%29%5E2=0\"$
\n" ); document.write( " $\"x%2B3=0\"$
\n" ); document.write( "Solve for x.
\n" ); document.write( "Then find y using the second equation.
