Question

How do you simplify `6 sqrt5 - 2sqrt5`?

Answer 1

It's pretty simple, actually: `6sqrt5- 2sqrt5=4sqrt5`

Explanation:

What we can do, is we can create a variable for the `sqrt5` and then substitute back after we do the math.

Let's say `x` can be equal to `sqrt5`. So then our simplified question would read: `6x-2x` when we place `x` in for the `sqrt5`.

`6x-2x=4x` so then we just take the `sqrt5` and place it back in for the `x` and we get `4sqrt5`.

Answer 2

4`sqrt`5

Explanation:

`sqrt`5(6-2) = 4`sqrt`5
