Question

Subtract the following polynomials, then place the answer in the proper location on the grid. Write your answer in descending powers of x.

Subtract 2x^2 - 6x - 4

from 4x^2 - 4x + 3.

Answer 1

`-2x^2-2x-7`

Like Terms:

- (
`2x^2` and
`4x^2`)

- (
`-6x` and
`-4x`)

- (
`-4` and
`3`)

Explanation:

`(2x^2-6x-4)-(4x^2-4x+3)` Write the trinomial

`2x^2-6x-4-4x^2+4x-3` Use distributive property

`-2x^2-2x-7` Combine like term

Answer 2

2x^2 + 2x +7

Explanation:

4x^2 - 2x^2 = 2x^2

4x - (-6x) = 2x

3 - (-4) = 7
