To simplify the expression (x^2 - 3x - 18) / (x + 3), we can first factor the numerator:
x^2 - 3x - 18 = (x - 6)(x + 3)
Now we have:
(x - 6)(x + 3) / (x + 3)
We can cancel out the common factor of (x + 3) from the numerator and denominator:
= x - 6
Therefore, the simplified expression is x - 6.
x^2-3x-18 / x+3
