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? Squaring? (How?), Factoring (How?)

Question 101751: Please help us solve...
(2z+3)^(2/3) + (2z+3)^(1/3) = 6
We've tried cubing each side which gets rather complicated, and we've tried factoring out a (2z+3)^(1/3), but we're not making any progress. Dad is helping, but he's having a tough time remembering complex radical problems!

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.
