Question

How do you simplify `5( x + 6) + 2a ( x + 6)`?

Answer 1

`(2a+5)x+12a+30`

Explanation:

multiply the `5` by everything in the brackets next to it, this gives `5x+30`
multiply 2a by everything in the bracket next to it, this gives `2ax+30`

add everything together to give `5x+30+2ax+12a`
factorise the x to give `(5+2a)x+12a+30`.

Answer 2

`(x+6)(5+2a)`

Explanation:

`5color(red)((x+6))+2acolor(red)((x+6))`

Take `color(red)((x+6)` common from both terms, leaving `5` and `2a`.

`color(red)((x+6))(5+2a)`

That's it,
Hope this helps :)
