This is what is known as the vertex form of a quadratic equation: it is for finding the vertex (obviously). Given the expression (x+a)^2+b, the vertex of this quadratic is (-a,b). So, the b …

First, let's compare with the general form: f ( x ) = a | x − h | + k The value of a is 1 , so the graph opens upwards with a slope of 1 (to the right of the vertex).

Vertex form introduction - Khan Academy
Finding the vertex of the quadratic by using the equation x=-b/2a, and then substituting that answer for y in the orginal equation. Then, substitute the vertex into the vertex form equation, …

While it is easier to shift in vertex form it can be done in any form. Shifting to right affects the x such that you subtract (because 1-1=0), so they correctly shift x by substituting x-1 …
