Question

How do you multiply `2(x+3)`?

Answer 1

`2x+6`

Explanation:

Multiply the contents of the brackets by 2

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Compare to the word phrase of "two apples"

We do not say "two of apples"

Nor do we say "two times apples"

So `2(x+3)` is saying the same thing. In that we have two of `(x+2)`.

Write as`" "x+3`
`" "underline(color(white)(.)x+3)" "larr" add"`
`" "2x+6`
