Hi there!
[tex]\large\boxed{(3) \text{ } 4x^{3} - x^{2} + 3x + 13}[/tex]
Given:
A = 6x³ - x² + 4x + 8
B = 2x³ + x - 5
Find A - B by subtracting the two equations. Subtract like-terms:
6x³ - x² + 4x + 8 - (2x³ + x - 5)
Simplify:
6x³ - x² + 4x + 8 - 2x³ - x + 5 =
4x³ - x² + 3x + 13. The correct choice is 3.
