Question #f220a

Answer 1

See explanation. If what you meant was different to how I interpreted it, edit the question and let me know.

Explanation:

To do maths formatting open and close with the hash symbol
So if I write hash 2x xx 3 hash I get: `2x xx 3`. Also look at
https://socratic.org/help/symbols

Assumption: you meant `(2xx2-11x)+(4xx2-4)`

In this case it is

`(4-11x)+(8-4)`

`4-11x+4`

`4+4-11x`

`8-11x`
