Answer:
6, -6
Step-by-step explanation:
We can use the equation x = (-b ± √b^2 - 4ac) / 2a. Quadratic equations can take the form ax^2 + bx + c = 0. In this case, a = 4, b = 0, and c = -144. Plug them in and you have
(0 ± √4^2 x 12 ^ 2) / 8
(0 ± 48) / 8
-48 / 8 = -6
48 / 8 = 6
The roots are 6 and -6.
