how to add or subtract

Question

(4x^2-2x-1)-(-3x^3+2)

Answer 1

To add or subtract polynomials, we need to combine like terms with the same variable and power.

First, let's distribute the negative sign to every term inside the parentheses:

(4x^2 - 2x - 1) + 3x^3 - 2

Now we can rewrite the expression with the like terms together:

3x^3 + 4x^2 - 2x - 1 - 2

Simplifying further:

3x^3 + 4x^2 - 2x - 3

Therefore, the result of (4x^2-2x-1)-(-3x^3+2) is 3x^3 + 4x^2 - 2x - 3.
