Final answer:
(x^2 + 2x - 3)/(x + 3) = (x - 1).
Step-by-step explanation:
To solve the equation (x^2 + 2x - 3)/(x + 3), we can factor the numerator and then cancel out common factors with the denominator.
The numerator can be factored into (x + 3)(x - 1).
Canceling out the common factor of (x + 3):
(x + 3)(x - 1) / (x + 3)
= (x - 1)
The simplified expression will be (x - 1).
