\n" ); document.write( "\n" ); document.write( "So I was on your website, practicing solving quadratics by completing the square (as you do) and I ran in to a problem. I had done this:\r
\n" ); document.write( "\n" ); document.write( "\"2x%5E2%2B12x%2B20=0\"
\n" ); document.write( "\"x%5E2%2B6x%2B10=0\"
\n" ); document.write( "\"%28x%5E2%2B6x%2B9%29%2B10-9=0\" (where the nines are b/2^2)
\n" ); document.write( "\"%28x%2B3%29%5E2=-1+\"\r
\n" ); document.write( "\n" ); document.write( "What do I do now that there's a negative number on the right side? I can't square root both! HELP!!\r

You can put this solution on YOUR website!
If you find the determinant of this quadratic equation \"D=6%5E2-4%2A1%2A10=-4%3C0\".\r
\n" ); document.write( "\n" ); document.write( "We answered that this quadratic equation has no real solution.\r
\n" ); document.write( "\n" ); document.write( "If you know the complex numbers you can find the complex roots.\r
\n" ); document.write( "\n" ); document.write( " \"x=3%2Bi\" and \"x=3-i\" where \"i=sqrt%28-1%29\".
