Question

Write 8n^2-13n+5 in factor form

Answer 1

`(8n - 5)(n-1)`

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

• 
  `8n^2 - 13n + 5`
• 
  `8n^2 - 8n - 5n + 5`
• 
  `8n(n -1) -5(n - 1)`
• 
  `(8n - 5)(n-1)`

The factored expression is
`(8n - 5)(n-1)`.
