can sb help me?İ have to make a project....
4.power polinoms i have to find the real roots an complex root.
anybody any idea for these.
Thanks....!

Does your project require you to write the program to solve the polynomial, or does it just require the roots (regardless of how you got them)?
What have you done so far?
What do you already know about a 4th power poly... ?
Can you (differentiate and) find the max (extreme points -> if the graph of y = ax^4 + bx^3 + cx^2 +dx + e opens down) ... or min ... if it opens up ?
From the extreme points ... and it it opens up or down ... can you see if it (touches or) crosses the x-axis ( ... so will have (1 or more) real roots then ... the rest imaginary <--always in pairs ,,,
Time to get back to basic calculus I think... Gah! I have forgotten so much! :-)
I just remembered this link re. Newton's Method of Finding Roots ...
