## Comment on

Root in the Denominator## calculation on 01:27 is not

## When simplifying expressions,

When simplifying expressions, we need to add like terms.

For example, 2x + 2y - y - 3x simplifies to be x - y. We combine the 2x and -3x separately and we must combine 2y and -y separately.

You are combining ALL of the terms.

So, when simplifying 2 + 2√3 - √3 - 3, we must combine the two like terms 2√3 and -√3. We get 1√3.

Then we combine 2 and -3 to get -1

So, altogether, 2 + 2√3 - √3 - 3 = -1 + √3

Does that help?

## do you believe we have enough

## Yes, you should have enough

Yes, you should have enough time . . . as long as it doesn't take you too long to see what steps are required.
