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?

Cphill didn't get hacked, he decided to take a rather (long) break, maybe since he's busy.

His account is still mod, you can see it since it has a knight in the top right corner.

He's not banned, he's still here with every post.

Please check your sources next time.
