-6$x^{3}$ - 3$x^{2}$ - 4x + 4
1. Distribute negative signs -(8$x^{3}$ + x - 3) + (2$x^{3}$ + $x^{2}$) - (4$x^{2}$ + 3x - 1) = -8$x^{3}$ - x + 3 + 2$x^{3}$ + $x^{2}$ - 4$x^{2}$ - 3x + 1 2. Group like terms together. (-8$x^{3}$ + 2$x^{3}$) + ($x^{2}$- 4$x^{2}$) + (-x - 3x) + (3 + 1) 3. Add like terms. -6$x^{3}$ - 3$x^{2}$ - 4x + 4
