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 :)
