Answer:
(x-3)(x+6)
Step-by-step explanation:
Given the polynomial: x²+3x-18
To factor it, first, we multiply the first and last terms.
Next, we list add factors of -18.
Next, we determine the factors that add up to the middle term: 3x
These factors are: 6x and -3x.
Replacing the middle term, we have:
