Simplify.(2x - 10) - (3x^2 + 10x) + (2x^3+ 3x^2)
A) 2x^3 - 8x - 10
C) 2x^3 + 6x^2 + 12x - 10
B) 2x^3- 6x^2 + 12x -10
D) 2x^2- 8x - 10

(I'll give brainliest to the correct answer :3)

A

Step-by-step explanation:

Let's first expand these parentheses. Remember that when we have a negative sign in front of a parentheses, that means we're multiplying each term within the parentheses by -1:

2x - 10 -3x^2 - 10x + 2x^3 + 3x^2

Now combine like terms. Like terms are the ones that have the same degree of x: 2x and -10x are like terms; -10 is by itself; -3x^2 and 3x^2 are like terms; 2x^3 is by itself. So:

2x^3 + (-3x^2 + 3x^2) + (2x - 10x) - 10

2x^3 - 8x - 10

Thus, the answer is A.
