Is "enzyme + substrate → enzyme + product 1 + product 2" a hydrolysis? Can you explain why?
Also please explain Enzyme + substrate 1 + substrate 2 → enzyme + product. Is it a dehydration synthesis? I have a bio test soon and I want to understand this... thanks :)

1. E + S <--> ES <--> E + P1 + P2
It could be a hydrolysis, but it doesn't have to be. Because this seems like an intro bio course, in your case, it is. The enzyme has a "water" at its active site that is breaking the bonds between the subunits of the substrate. What is really going on is covered in more advanced chem and biochem.
2. E + S1 + S2 <--> S2-E-S1 <--> E + P
Yes. This could be a dehydration/condensation synthesis reaction. Water is lost to form bonds between the two substrates.
If YA had a drawing capability, I could draw this out for you. You can find pictures on googles comparing condensation and hydrolysis.
