Practice Problems: 1) Simplify: (x3 + 3x2 – 4) – (x2 + x3) (don’t forget to distribute the – sign) 2) When can you combine variables? What happens when you multiply variables with the same bases? What happens when you add variables with the same base? What happens when you divide variables with the same base? (Look at your properties to help you) 3) Simplify: x4 + x3x3 + x2 + 4x4 – x2 + x6 4) Simplify: 4x4 + 5x4 5) Simplify: x + x + x2 – x3
