text: answer this only if you are brave enougth? i asked a maths question here a week or two ago and it was answered correctly within about 15 minutes, so i have decided to ask a much harder question. in school i used to solve similtanious equations, since school i have learned about complex numbers, i have decided to mix the two areas to produce a similtanious complex equation, the first to give a correct answer gets the 10 points :  x squared + y + 40 + 32 i = -5 x + y squared + 53 + 107 i = 10 i  solve both x and y (both are complex numbers) hopefully this question is hard enougth to keep you going for longer. only try this if you want a challenge. i recommend making it easier.  x²+y=m; x+y²=n. m is -45-32i; n is -53-97i.  then i got y²=m²-2mx²+x^4. x+m²-2mx²+x^4=n.  or x^4-2mx²+x+ (m²-n) = 0.
