Given, x² + 3x - 54 = 0
--> x² + 9x - 6x - 54 = 0
--> x(x + 9) - 6(x + 9) = 0
--> (x - 6)(x + 9) = 0
x = 6 , x= -9
So, X = 6

Step-by-step explanation:
By Quadratic formula,
x= -3±√3^2-4*1(-54)/2*1
x=-3±15/2
One with a Add and the other with a Substract-
x=-3+15/2=6
x=-3-15/2=-9
Valves of x is:-
x=6 &
x=-9
