Question

How do you write `(5k + 2)(3k + 1)` in standard form?

Answer 1

`15k^2 + 11k + 2`

Explanation:

Use FOIL, or in other words, distribute the terms in the first parenthesis to the terms in the second parenthesis.

So this would be:
`(5k + 2)(3k + 1)`

`5k(3k) + 5k(1) + (2)(3k) + 2(1)`
`15k^2 + 5k + 6k +2`
`15k^2 + 11k +2`
