Answer:

[tex]2x^2-6[/tex]

Step-by-step explanation:

If a quadratic equation has a root at a certain point, the x value must equal. zero.  If we want to have the function reach 6 and -6 as roots:

x = 6

x - 6 = 0

x = -6

x + 6 = 0

Combining the two we get (x+6)(x-6) which will give us a quadratic equation.

Expanding: [tex]x^2-6x+6x-6 = x^2-6[/tex]

The leading coefficient is the number before the variable with the highest power, which is 2: [tex]2x^2-6[/tex]
