HURRY PLEASE_in the first quadrant, you start on (1,2) and move three units right what point do you end up on?

(4.2) this the answer

Step-by-step explanation:

First we rin through x line by 3 so we add 3 to 4 give 4

First observe that x=-1 is a root of the equation. Use long division to divide x^3-3x^2+x+5 by x+1, we find that (x^3-3x^2+x+5)/(x+1)=(x^2-4x+5). Now we need to find the roots of x^2-4x+5.
x^2-4x+5=0, 
x^2-4x+4=-1,
(x-2)^2=i,
x-2=i or -1,
x=2+i or 2-i. 
The three roots are 2+i, 2-i, -1.
