Here's the answer. I was expecting that no one here can solve the 3rd one, but to my surprise, no one can solve the easy 2nd one either. So disappointing

Problem set #2
Solve for x,y,z and v, w depending on the problem.
Medium: x + y = 2 xy = 2
Difficult: x + y + z = 3 xy + yz + xz = 6 xyz = 3
Ex Difficult: x + y + z + v = 4 xy + xz + xv + yz + yv + zv = 12 xyz + xyv + xzv + yzv = 16 xyzv = 4

I'm too young to solve any besides the first one.

LoL, these problems are not even that hard, well except for the "extremely difficult" one, i theoritically know how to solve it, but when i put it in my computer (pentium, 2.5 Ghz), and tell it to solve, it takes .... 30 mins and frozed, lol. But the 1st and the 2nd one is do-able practically. Common somebody out there...

im 14 too....and the first is 1 +/- 2i where if x is 1+2i, then y has to be 1-2i
will do second later

My Algebra 2's beyond rusty, but I'll give it a shot. 1) x + y = 2 xy = 2 y = 2 - x x(2 - x) = 2 2x - x 2 = 2 x 2 + 2x = 2 x 2 + 2x + 4 = 2 + 4 (x + 2) 2 = 6 x + 2 = +/- sqrt 6 x = -2 +/- sqrt 6 Nevermind, I did it all wrong...

I can do math! The answer for the medium is undefined. Moving on to difficult...
