<span>y = -x3 + 5x2 - 11x + 55 ||x = 5 one root -125 + 125 - 55 + 55 = 0
using Synthetic Divsion
5 -1 5 -11 55
-5 0 -55
</span><span>-1 0 -11 0
results in:
-x^2 - 11 = 0
x^2 + 11 = 0
x^2 = -11
x = ± i√11
roots are: i√11,-i√11,5</span>
In order to do this you can <span>factorise it to get
(x+1)^2 + (y-5)^2 = 16 = 4^2
hence centre is (-1,5) and radius is 4
