Question

Subtract these polynomials (3x^3-4x^2+x-2)-(x^3-5x^2+3x+2)

Answer 1

The answer is 2x^3 + x^2 -2x - 4

Answer 2

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

Explanation:

Given the expression:

`(3x^3-4x^2+x-2)-(x^3-5x^2+3x+2)`

It is important to remember the multiplication of signs:

`(+)(+)=+\\(-)(-)=+\\(+)(-)=-`

Then, knowing this, we can distributive the negative sign:

`=3x^3-4x^2+x-2-x^3+5x^2-3x-2`

The final step is to add the like terms. Then we get:

`=2x^3+x^2-2x-4`
