Question

How do you factor `5x-4`?

Answer 1

There are no simple factors of `5x-4`

Explanation:

You could "factor" `5x-4` by dividing the expression by any constant.
For example:
[1] dividing by `(-1)` would give `(-1)(4-5x)`

[2] dividing by `5` would give `(5)(x-4/5)`

[3] dividing by `4` would give `(4)(5/4x-1)`

[2] dividing by `27` would give `(27)(5/27x-4/27)`

Technically these are all valid "factorings" but they are no real improvement over the given version.
