Question

How do you factor `3m^4+243`?

Answer 1

`3(m^4 + 81)`

Explanation:

No `m` can be factored out of both terms, since `m` isn't a factor of `243` (it's a variable). So, since `243` is divisible by `3`, we can factor a `3` out of the entire equation, put the rest in parentheses, and divide each term with `3` as such:

`3(m^4 + 81)`
