Question

How do you simplify `3sqrt10 + 7sqrt15 - 6sqrt10 - 4sqrt15`?

Answer 1

`color(red)(-3sqrt(10))color(green)(+3sqrt(15))`

Explanation:

You would sum the like terms:

`color(red)(3sqrt(10))color(green)(+7sqrt(15))color(red)(-6sqrt(10))color(green)(-4sqrt(15))`

Then

`-3sqrt(10)+3sqrt(15)`
