Answer:

(x + 1)² + 4

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a (x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

to obtain this form use the method of completing the square

• add/subtract (half the coefficient of the x-term)² to x² + 2x

= x² + 2(1)x + 1 - 1 + 5

= (x + 1)² + 4 ← the second option
