Hey there! :)

5n(3n - n + 8)

Simplify.

(5n × 3n) + (5n × -n) + (5n × 8)

Simplify.

(15n²) + (-5n²) + (40n)

Remove parenthesis

**Remember : a negative times a positive is always a negative, a positive times a positive is a positive, and a negative times a negative is a positive**

15n² - 5n² + 40n

Combine like terms.

(15n² - 5n²) + 40n

Simplify.

10n² + 40n → final answer :)

~Hope I helped!~
