x^2-3x-18 / x+3

1 answer

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.
