Question

Simplify the expression.
$left parenthesis 3 – 6 straight n to the power of 5 – 8 straight n to the power of 4 right parenthesis – left parenthesis negative 6 straight n to the power of 4 – 3 straight n – 8 straight n to the power of 5 right parenthesis$

$3 n^{4} + 3$
$4 n^{5} + 2 n + 5$
$n^{5} + 2 n^{4} + 1$
$2 n^{5} - 2 n^{4} + 3 n + 3$

hint Hint:

Combine like terms

The correct answer is: $2 straight n to the power of 5 – 2 straight n to the power of 4 plus 3 straight n plus 3$

$left parenthesis 3 – 6 straight n to the power of 5 – 8 straight n to the power of 4 right parenthesis – left parenthesis negative 6 straight n to the power of 4 – 3 straight n – 8 straight n to the power of 5 right parenthesis$
$3 minus 6 n to the power of 5 minus 8 n to the power of 4 plus 6 n to the power of 4 plus 3 n plus 8 n to the power of 5$
$left parenthesis negative 6 straight n to the power of 5 plus 8 straight n to the power of 5 right parenthesis plus left parenthesis negative 8 straight n to the power of 4 plus 6 straight n to the power of 4 right parenthesis plus left parenthesis 3 straight n right parenthesis plus 3$
$equals 2 straight n to the power of 5 – 2 straight n to the power of 4 plus 3 straight n plus 3$
