Rewrite equation in vertex form y=x^2+4x+2

Steps:

The general vertex form of a parabola is as follows:

where xv is the x coordinate of the vertex, a is the coefficient determining how wide/narrow the parabola is and whether it is open-up (+) or open-down (-), and b is the bias (vertical shift.

Transforming an expression into the vertex form involves completing the square step:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
