Question

Simplify (2x³–3x²+6x – 14)-(3x²–2x - 5) - - OA O A. 2x³-6x²+8x–9 O B. 2x³-6x²+8x +9 OC. 2x³+6x²,8x-9 OD. 2x³-6x²-8x -9

Answer 1

`2x^(3) -6x^2+8x-9`

Explanation:

`2x^(3)` has no other like terms with it so for the first part it's just
`2x^(3)`

`-3x^2-3x^2=-6x^2`

`6x-(-2x)=8x` (Two negative signs make a positive which means addition)

`-14-(-5) = -9` (AGAIN, two negative signs make a positive which means addition)

Combine everything and

Your final answer should be
`2x^(3) -6x^2+8x-9`
