Answer:
line of symmetry , x = 3
Step-by-step explanation:
Standard form of quadratic equation is y = ax^2 + bx + c, where a, b, and c equal all real numbers. You can use the formula x = -b / 2a to find the line of symmetry.
[tex]y = (x+ 2)(x-8)\\\\y = (x^2 -8x + 2x -16)\\\\y = x^2 -6x -16[/tex]
a = 1, b = -6, c = -16
Line of symmetry is ,
[tex]x = -\frac{b}{2a} = -\frac{-6}{2} = 3[/tex]
