$\"+x%5E2+%2B+298x+%2B+600+\"$
\n" ); document.write( "Set it equal to zero, then
\n" ); document.write( "subtract $\"+600+\"$ from both sides
\n" ); document.write( " $\"+x%5E2+%2B+298x+=+-600+\"$
\n" ); document.write( "Complete the square
\n" ); document.write( "Take 1/2 of $\"+298+\"$ , square it,
\n" ); document.write( "then add it to both sides
\n" ); document.write( " $\"+x%5E2+%2B+298x+%2B+%28298%2F2%29%5E2+=+-600+%2B+%28298%2F2%29%5E2+\"$
