You can put this solution on YOUR website!
you cannot factorise this quadratic easily, so look to the quadratic formula to help you. By looking at the discriminant, $\"b%5E2+-+4ac+\"$ , we see that it is\r

\n" ); document.write( "\n" ); document.write( " $\"+%286%29%5E2+-+4%281%29%28-3%29+\"$
\n" ); document.write( " $\"+36+%2B+12+\"$
\n" ); document.write( " $\"+48+\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So, the quadratic does have solutions, given by:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"+x+=+%28-b+%2B-+sqrt%28b%5E2-4ac%29%29%2F%282a%29+\"$
\n" ); document.write( " $\"+x+=+%28-6+%2B-+sqrt%2848%29%29%2F2+\"$
\n" ); document.write( " $\"+x+=+%28-6+%2B-+sqrt%2816%2A3%29%29%2F2+\"$
\n" ); document.write( " $\"+x+=+%28-6+%2B-+sqrt%2816%29sqrt%283%29%29%2F2+\"$
\n" ); document.write( " $\"+x+=+%28-6+%2B-+4sqrt%283%29%29%2F2+\"$
\n" ); document.write( " $\"+x+=+%282%28-3+%2B-+2sqrt%283%29%29%29%2F2+\"$
\n" ); document.write( " $\"+x+=+-3+%2B-+2sqrt%283%29+\"$
\n" ); document.write( "so $\"+x+=+-3%2B2sqrt%283%29+\"$ or $\"+x+=+-3-2sqrt%283%29+\"$ \r
