Question

Add the following polynomials, then place the answer in the proper location on the grid.

2x3 - 4x2 + 6x - 3
29 +6x2 - 8x + 12
- 3x3 + 2x2 - 4x - 7
Help ????????

Answer 1

4x^2-6x+2

Explanation:

Answer 2

`x^3 - 6x + 2`

Explanation:

The given polynomials can be added together by adding like terms together as shown below:

=> Add together, the coefficient of all terms that have the power of 3.

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

`2x^3 + x^3 - 3x^3`

`3x^3 - 3x^3`

`x^3`

=>
`(-4x^2) + (6x^2) + (2x^2)`

`-4x^2 + 8x^2`

`4x^2`

=>
`(6x) + (-8x) + (-4x)`

`6x - 8x - 4x`

`-6x`

=>
`(-3) + (12) +(-7)`

`-3 + 12 - 7`

`2`

The answer =
`x^3 - 6x + 2`
