How do you factor #5x-4#?

Answer 1

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

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.

To factor (5x - 4), you can simply rearrange the terms:

(5x - 4 = 5x + (-4))

So, the factored form of (5x - 4) is (5x + (-4)).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
