Divide.%0D%0A%0D%0A(3x3 + 10x2 – 12x – 5) ÷ (3x + 1)%0D%0A(1 point)

Answer 1

To divide (3x^3 + 10x^2 - 12x - 5) by (3x + 1), we can use long division.

x^2 - x + 3
_____________________________
3x + 1 | 3x^3 + 10x^2 - 12x - 5
- (3x^3 + x^2)
______________
9x^2 - 12x
- (9x^2 + 3x)
__________
-15x - 5
-(-15x - 5)
__________
0

Therefore, the result after dividing is x^2 - x + 3.
