x^2 + 18x + 81 = 25
x^2 + 18x + 81 - 25 = 0
x^2 + 18x + 56 = 0
(x + 4)(x + 14) = 0
x = -4 or x = -14

-x^3 + 5x^2 - 11x + 55 = 0
-x^2(x - 5) - 11(x - 5) = 0
(x - 5)(-x^2 - 11) = 0
x - 5 = 0 or -x^2 - 11 = 0
x = 5 or x = ± (sqrt 11)i

x^3 - 2x^2 + 10x + 136 = 0
(x + 4)(x^2 - 6x + 34) = 0
x + 4 = 0 or x^2 - 6x + 34 = 0
When x + 4 = 0, x = -4
When x^2 - 6x + 34 = 0
x = [6 ± sqrt (-100)]/2 = (6 ± 10i)/2 = 3 ± 5i
The solution is {-4, 3 + 5i, 3 - 5i)
