You can put this solution on YOUR website!
$\"2x%5E2+%2B+3x+%2B+4+=+0\"$
\n" ); document.write( "divide both sides by 2
\n" ); document.write( " $\"x%5E2+%2B+%283%2F2%29x+%2B+2+=+0\"$
\n" ); document.write( "subtract 2 from both sides
\n" ); document.write( " $\"x%5E2+%2B+%283%2F2%29x+=+-2\"$
\n" ); document.write( "divide the coefficient of x by 2, square it, and add it to both sides
\n" ); document.write( " $\"x%5E2+%2B+%283%2F2%29x+%2B+9%2F16=+-2+%2B+9%2F16\"$
\n" ); document.write( " $\"%28x+%2B+%283%2F4%29%29%5E2+=+-23%2F16\"$
\n" ); document.write( "If you take the square root of both sides,
\n" ); document.write( "the solution for x is imaginary \n" ); document.write( "
