Question

simplify the expression.
$(4n^4 - 8n + 4) - (8n^2 + 4n^4 + 1)$
$-7n^2 - 4n + 3$
$-7n^2 - 8n + 3$
$-6n^2 - 8n + 3$
$-8n^2 - 8n + 3$

Explanation:

Step1: Distribute the negative sign

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

Step2: Combine like $n^4$ terms

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

Step3: Combine constant and linear terms

$0n^4 - 8n^2 - 8n + 3$

Answer:

$-8n^2 - 8n + 3$
