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

Answer:

2x^2 + 2x +7

Step-by-step explanation:

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

4x - (-6x) = 2x

3 - (-4) = 7

Answer 2

Answer:

$-2x^2-2x-7$                                        

Like Terms:

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

- ($-6x$ and $-4x$)

- ($-4$ and $3$)

Step-by-step 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
