Add or subtract
(4x^2-2x-1)-(-3x^3+2)
First, we need to distribute the negative sign inside the parentheses:
(4x^2 - 2x - 1) + (3x^3 - 2)
Now we can combine like terms:
3x^3 + 4x^2 - 2x - 1 - 2
Simplifying further:
3x^3 + 4x^2 - 2x - 3
To add or subtract the given expressions, we need to combine like terms.
First, let's rearrange the terms in descending order of exponent:
(4x^2 - 2x - 1) - (-3x^3 + 2)
Now, let's distribute the negative sign to the terms inside the parentheses:
(4x^2 - 2x - 1) + (3x^3 - 2)
Now, let's combine like terms together. We add or subtract the coefficients of the terms with the same degree of x:
(3x^3 + 4x^2) + (-2x - 2 - 1)
Now, let's rearrange the terms again:
3x^3 + 4x^2 - 2x - 2 - 1
Finally, let's combine the constants together:
3x^3 + 4x^2 - 2x - 3
Therefore, the simplified expression is 3x^3 + 4x^2 - 2x - 3.
