Answer
x times y = xy
x + y times a + b = (x + y)(a + b)
For that you can use the FOIL method which is First, Outside, Inside, Last.
First: x times a = ax
Outside: x times b = bx
Inside: y times a = ay
Last: y times b = by
So you have ax + bx + ay +by.
If you end up using numbers, then you can simplify.
Ask your teacher or parents. It's easier to explain in person.
