To solve the equation x^2 - 3x - 18 = 0, we can use factoring or the quadratic formula.

Factoring:
We need to find two numbers that multiply to -18 and add up to -3. The numbers -6 and 3 satisfy these conditions, so we can rewrite the equation as:
(x - 6)(x + 3) = 0

Setting each factor equal to zero, we have:
x - 6 = 0 or x + 3 = 0

Solving these equations, we find:
x = 6 or x = -3

Therefore, the solutions to the equation x^2 - 3x - 18 = 0 are x = 6 and x = -3.
