Question

Use axis of symmetry formula to find the axis of symmetry of the following equation.

(Just give the number. Do not put x =)
x2 + 10x + 26

Answer 1

-5

Explanation:

The square of x is written x^2. Thus, we have x^2 + 10x + 26 here. Using the axis of symmetry formula x = -b/(2a), we get:

-10

----- = -5
