Solve for x using:
First, we need to identify a, b and c
The general form of a quadratic equation is:
So, by comparison with
Substitute these values of a, b and c in
Split the expression to two
or
To solve further in decimal form, we have

Answer:
x = - 3 ± √27 or if you want it in decimal form correct to nearest hundredth:
x = -8.20, 2.20.
Step-by-step explanation:
x^2 + 6x - 18 = 0
this will not factor so we use completing the square:
x^2 + 6x = (x + 3)^2 - 9 so:
(x + 3)^2 - 9 - 18 = 0
(x + 3)^2 = 27
x+ 3 = ±√27
x = - 3 ± √27
