Answer:
{-6, - 6}
Step-by-step explanation:
Reduce this equation by dividing all 4 terms by 2:
x^2 + 12X + 36 = 0
Note that the quadratic can be rewritten as the square of a binomial:
(x + 6)^2 = 0 => (x + 6) = ±0
This in turn results in x = -6 and x = -6 (a double, real root).
Of the given solutions, (-6, 0) is the best if you want a point on the graph. If you want just a numerical solution, -6 is acceptable.
