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.

$y = (x+ 2)(x-8)\\\\y = (x^2 -8x + 2x -16)\\\\y = x^2 -6x -16$

a = 1, b = -6, c = -16

Line of symmetry is ,

$x = -\frac{b}{2a} = -\frac{-6}{2} = 3$
