If bank charges 4 dollars under account of 100 dollar

Lisae's account balance decrease at 4$. Then Lisae have 11$

x = ± 6i

step-by-step explanation:

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

x = ± 6i

answer: i'm not sure
