The sum of the roots of $\"ax%5E2%2Bbx%2Bc+=+0\"$ ?\r
\n" ); document.write( "\n" ); document.write( "Since the the roots are given by:
\n" ); document.write( " $\"x+=+%28-b%2Bsqrt%28b%5E2-4ac%29%29%2F2a\"$ and $\"x+=+%28-b-sqrt%28b%5E2-4ac%29%29%2F2a\"$
\n" ); document.write( "Their sum is:
\n" ); document.write( " $\"%28%28-b%2Bsqrt%28b%5E2-4ac%29%29%2F2a%29+%2B+%28%28-b-sqrt%28b%5E2-4ac%29%29%2F2a%29\"$ = $\"-2b%2F2a+=+-b%2Fa\"$
