Write x2 - 8x + 13 = 0 in the form (x - a)2 = b, where a and b are integers.

(x - 4)2 = 3

(x - 3)2 = 2

(x - 2)2 = 1

(x - 1)2 = 4

The question is asking to write x^2-8x+13 in the form of (x-1)2 = b where as a and b are integers, base on the said formula, I would say that the correct answer would be (x - 4)2 = 3, I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications
