question\nfactor.\n$x^2 + 3x - 18$

Explanation:

Step1: Find two numbers

We need two numbers that multiply to -18 and add up to 3. The numbers are 6 and -3 since (6\times(-3)= - 18) and (6+( - 3)=3).

Step2: Factor the quadratic

Using the numbers found, we can factor the quadratic (x^{2}+3x - 18) as ((x + 6)(x-3)).

Answer:

((x + 6)(x - 3))
