Rearrange the quadratic equation to: x2-6x-9 = 0 and use the quadratic equation formula to find the values of x which are:-
x = -1.2426406871 or x = 7.2426406871
When factored: (x+1.2426406871)(x-7.242406871) = 0

With great difficulty not knowing if 6x and 27 are plus or minus
-x(x2 - 2)(x2 + 3)
x2+6x-7 = (x+7)(x-1) when factored
x(6x - 11)
(x - 6)(x2 + 6x + 36)
