Answer: D - 6x^2 + 5x - 4/15
Explanation:
To simplify the expression (8x^2 - 3x + 1/3) - (2x^2 - 8x + 3/5), we can combine like terms within the parentheses
8x^2 - 3x + 1/3 - 2x^2 + 8x - 3/5
Next, we can combine the like terms
(8x^2 - 2x^2) + (-3x + 8x) + (1/3 - 3/5)
Simplifying
6x^2 + 5x + (5/15 - 9/15)
The fractions can be simplified further
6x^2 + 5x + (-4/15)
Thus, the simplified expression is 6x^2 + 5x - 4/15
