The roots of \(x^2 +px + q = 0\) are real, where p and q are real numbers. Prove that the roots of \(x^2 + px + q + (x + a)(2x + p) = 0\)
are real, for any real number.
Thanks! Also what happened to CPhill?
I think he got hacked.
Cphill didn't get hacked, he decided to take a rather (long) break, maybe since he's busy.
