You can put this solution on YOUR website!
well first clear the fraction
\r
\n" ); document.write( "\n" ); document.write( "(x^2+7x)/3 = -4
\n" ); document.write( "3((x^2+7x)/3 = -4)
\n" ); document.write( "x^2+4x=-12
\r
\n" ); document.write( "\n" ); document.write( "now simplify and solve using the quadratic formula but you will find there is no solution
\r
\n" ); document.write( "\n" ); document.write( "x^2+4x+12=0
\r
\n" ); document.write( "\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\r
\n" ); document.write( "\n" ); document.write( "where a = 1, b = 4, & c = 12
\r
\n" ); document.write( "\n" ); document.write( " $\"x+=+%28-4+%2B-+sqrt%28+4%5E2-4%2A1%2A12+%29%29%2F%282%2A1%29+\"$
\n" ); document.write( " $\"x+=+%28-4+%2B-+sqrt%2816-4%2A12%29%29%2F%282%2A1%29\"$
\n" ); document.write( " $\"x+=+%28-4+%2B-+sqrt%2816-48%29%29%2F%282%29\"$
\n" ); document.write( " $\"x+=+%28-4+%2B-+sqrt%28-32%29%29%2F%282%29\"$
\r
\n" ); document.write( "\n" ); document.write( "since you can't take the square root of a negative number and get a real number back there are no real solutions. \n" ); document.write( "

\n" );
