Question

Add or subtract. (4x^2-2x-1)-(-3x^3+2)

Answer 1

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

Answer 2

that not an option

Answer 3

To subtract a negative, we can change it to addition and flip all the signs of the second expression:

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

Now we need to group like terms and combine them:

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

Final Answer: 3x^3 + 4x^2 - 2x - 2

Answer 4

To subtract a negative, we can change it to addition and flip all the signs of the second expression:

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

Now we need to group like terms and combine them:

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

Final Answer: 3x^3 + 4x^2 - 2x - 2

Answer 5

Since the options are not provided, we can factor out a common term to simplify the expression as follows:

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

= 4x^2 - 2x - 1 + 3x^3 - 2 (distributing the negative sign)

= 3x^3 + 4x^2 - 2x - 3 (combining like terms)

Therefore, the simplified form of the expression is:

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