Answer:
[tex](8n - 5)(n-1)[/tex]
Step-by-step explanation:
Hello!
We can factor this by grouping. We have to find two numbers that add up to -13 but multiply to 8 * 5 .
The two numbers that work are -8 and -5. Expand -13n to -8n and -5n.
Factor by Grouping
- [tex]8n^2 - 13n + 5[/tex]
- [tex]8n^2 - 8n - 5n + 5[/tex]
- [tex]8n(n -1) -5(n - 1)[/tex]
- [tex](8n - 5)(n-1)[/tex]
The factored expression is [tex](8n - 5)(n-1)[/tex].
