Get it in the form ax^2 + bx = c\r
\n" ); document.write( "\n" ); document.write( "\"16x%5E2+%2B+40x+=+-21\"
\n" ); document.write( "\"16%28x%5E2+%2B+expr%285%2F2%29x%29+=+-21\"
\n" ); document.write( "\"%28x%5E2%2Bexpr%285%2F2%29x%29+=+-21%2F16\"
\n" ); document.write( "Now it is time to complete the square:
\n" ); document.write( "Recall that \"+c++=+%28b%2F2%29%5E2\"
\n" ); document.write( "So \"%285%2F4%29%5E2+=+25%2F16\"
\n" ); document.write( "Remember to balance the equation by adding what we added to complete the square to both sides.
\n" ); document.write( "\"%28x%5E2+%2B+5x+%2B+expr%2825%2F16%29%29+=+expr%28-21%2F16%29+%2B+25%2F16\"
