solving equations with syntax: y(x+2)(x+2)
Do I foil the parentheses first? distribute the y on both? multiply y with one, the distribute to the second parentheses?

This is not an equation. It's called an expression. (All equations contain an equal sign.)
We do not solve expressions; we simplify them.
You can foil first. Then you will have:
y*(quadratic polynomial) and you can now distribute the y, to finish.
You can distribute first. Then you will have:
(linear binomial containing both x and y)*(x + 2) and you can now foil, to finish.
But do not distribute the y twice!
If this expression is, in fact, part of an equation to solve, then you might not need to foil or distribute. Please post the entire exercise.
