i'm not entirely sure
step-by-step explanation:
if you ask home depot or lowe's they might be able to you out
x = ± 6i
x^2 = -36
take the square root of each side
sqrt(x^2) = sqrt(-36)
we know sqrt(ab) = sqrt(a) sqrt(b)
x = ±sqrt(36) sqrt(-1)
we know that sqrt (-1) = i
the 4th choice is the correct one
nope lol
