 Question 100479: Let x(1) and x(2) be the real solutions to the equation x^2-sqrt(11)x+2=0 Then the sum x(1)+x(2) is equal to ? I have the answer, but have no idea how to get to it. I think the two solutions are: 1/2(-sqrt(2) + sqrt(11); converted to decimals: 0.951206 and 1/2 (sqrt(2) + sqrt(11); converted to decimals: 2.3654 So x(1)+x(2) = 3.316627 How to work this out?

 Question 102010: Let me try this again, I accidentally hit "Enter" before I got the problem typed in. Ok, Now I am drowning in confusion and frustration. I am not even sure how to type this prblem in here, so I am going to have to describe the symbol and I will Place the Letter "V" were the symbol goes. I believe the symbol is called a "Radican" or something like that: it looks like a square root and division symbol combined. SIMPLIFY BY RATIONALIZING THE DENOMINATOR???
