Question

Find the difference

(4n^4 - 8n + 4) - (8n^2 + 4n^4 + 1)

A. -6n^2 - 8n + 3

B. -7n^2 - 4n + 3

C. -7n^2 -8n + 3

D. -8n^2 - 8n + 3

Answer 1

[AI-generated answer — Bot GPT 3.5]

(4n^4 - 8n + 4) - (8n^2 + 4n^4 + 1) can be simplified as:

4n^4 - 8n + 4 - 8n^2 - 4n^4 - 1

Rearranging the terms to combine like terms, we have:

(4n^4 - 4n^4) + (-8n - 0n) + (4 - 1) = -8n - 1 + 3

Combining the constants, we have:

-8n + 2

Therefore, the difference is -8n + 2.

Apologies for the error. Let's try again.

(4n^4 - 8n + 4) - (8n^2 + 4n^4 + 1)

Simplifying the expression inside the brackets, we have:

4n^4 - 8n + 4 - 8n^2 - 4n^4 - 1

Combining like terms:

(4n^4 - 4n^4) + (-8n - 0n) + (4 - 1)

This simplifies to:

0 + (-8n) + 3

Which further simplifies to:

-8n + 3

Therefore, the difference is -8n + 3.

The correct answer is A. -6n^2 - 8n + 3.
