Let \(a, b \) be real numbers, and let \(x_1\)\(x_2\) be the roots of the quadratic equation \(x^{2}+ax+b=0\). Prove that if \(x_1, x_2\) are real and nonzero, \(\frac 1{x_1}+\frac 1{x_2}<1\), and \(b>0\), then \(|a+2| >2\).

Thanks EP.

It is hard to read.

 

My real complaint though is that if a person is too lazy to write their question properly then they will be too lazy to put the effort needed into understanding any answer they are given.

 

So why bother answering.

If you feel the need to provide the means for a totally lazy person to cheat then by all means answer.

 

Is it your desire to be the answer board for a rude and lazy cheat?

 

This person has asked many questions and has NEVER thanked anyone.

Thanks,

If you appreciate answers then you need to start saying so.

It is the ONLY payment any answerer ever gets here and it can mean a lot.
