Answer:
the quotient is 1 x^2 + 2 x + 3
Explanation:
Use synthetic division here; it's less work. Setting up synthetic division, we get:
-1 / 1 3 5 3
-1 -2 -3
-------------------------------------------
1 2 3 0
Since the remainder is 0, we know that x + 1 divides evenly into x^3 + 3x^2 + 5x + 3 and that the quotient is 1 x^2 + 2 x + 3
