You can put this solution on YOUR website!

\n" ); document.write( " $\"x%5E2+%2B+7x+-+1+=+0\"$
\n" ); document.write( "
You can use Quadratic Formula
\n" ); document.write( "ax^2 +bx + c = 0, therefore a = 1, b = 7 c = -1
\n" ); document.write( "
$\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( " $\"x+=+%28-7+%2B-+sqrt%28+7%5E2-4%2A1%2A-1+%29%29%2F%282%2A1%29+\"$
\n" ); document.write( " $\"x+=+%28-7+%2B-+sqrt%28+49%2B4%29%29%2F%282%29\"$
\n" ); document.write( " $\"x+=+%28-7+%2B-+sqrt%2853%29%29%2F%282%29\"$ \r
\n" ); document.write( "\n" ); document.write( "
You got the correct answer .\r
