**Math**

This is a mathematical expresion, not a question. If you copy the question from a book, most probably the instructions are at the beginning of a number of questions. It could be "simplify the following expressions:", or "factorize", etc. I assume it is "simplify". x + 3x^2 + x...

**algebra equations**

combine the like terms, making 2h=6. then simplify and you get h=3. once again, combine like terms, and you have 3x+2=-1. simplify. 3x=-3. simplify. x=-1
