To solve the equation (n^2 - 9n = -18), follow these steps:

- Move all terms to one side to set the equation to zero: (n^2 - 9n + 18 = 0).
- Factor the quadratic equation: ((n - 6)(n - 3) = 0).
- Set each factor equal to zero and solve for (n): [ \begin{align*} n - 6 &= 0 \implies n = 6 \ n - 3 &= 0 \implies n = 3 \end{align*} ]
- Therefore, the solutions to the equation are (n = 6) and (n = 3).
