Answer

-3$x^{3}$ + 6$x^{2}$ + x + 1

Work Step by Step

We write an expression to express this problem: (-3$x^{3}$ + 2$x^{2}$ + 7x - 1) - (-4$x^{2}$ + 6x - 2) = Use the distributive property: -3$x^{3}$ + 2$x^{2}$ + 7x - 1 + 4$x^{2}$ - 6x + 2 = Group similar terms. -3$x^{3}$ + (2$x^{2}$ + 4$x^{2}$) + (7x - 6x) + (-1 + 2) = Simplify. -3$x^{3}$ + 6$x^{2}$ + x + 1
