Answer:
n^2 - 5n - 24
Step-by-step explanation:
You can use FOIL to multiply the binomials.
FOIL stands for the 4 products you need to caclulate when multuiplying 2 binomials. It just reminds you todo the 4 needed multiplications.
F - first terms
O - outside terms
I - inside terms
L - last terms
F O I L
(n - 8)(n + 3) = n * n + 3 * n - 8 * n - 8 * 3
Now we simplify the products and collect like terms.
= n^2 + 3n - 8n - 24
= n^2 - 5n - 24
