Identify the axis of symmetry for the following equation:
y = x^2 + 10x + 26

A) x = -5

B) x = 2

The answer to your question is the letter A.

Step-by-step explanation:

Data

             y = x² + 10x + 26

Factor the right side of the equation

         y - 26 = x² + 10x

-Complete the perfect trinomial square

         y - 26 + (5)² =  x² + 10x + (5)²

-Simplify

        y - 26 + 25 = x² + 10x + 25

              y - 1 = (x + 5)²

Vertex = (-5 , 1)

The function given is a vertical parabola whose axis of symmetry goes through x = -5
