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
