Hi there,

I've been asked to calculate the roots of this equation by iteration (showing roots to 2d.p)

x^2 + 5x + 2 = 0

I try to look up the method on youtube and do it myself however I think I'm getting confused. I'll show what I have done below but if someone could offer some help with this subject I would greatly appreciate it. I'm struggling to understand where to even start really.

x^2 + 5x + 2 = 0

(x^2 + 5x + 2) / x = 0 / x

x + 5 + (2/x) = 0

x + (2/x) = -5

x = -5 - (2/x)

Can anybody tell me if this is right and where to go from here? If it's not right, where have I gone wrong?

Thanks,

Chris
