Answer: x = - 3
Step-by-step explanation:
The equation is in a standard form of equation as;
y = ax^2 + bx + c, and therefore, the axis of symmetry is given by the formula,
X = - b / 2a.
Therefore using that in the question, a = 1 and b= 6
Therefore, the axis of symmetry is:
x = - (6) / 2(1) which gives
x = - 3
