WebbThe Standard Form for writing a polynomial is to put the terms with the highest degree first. Example: Put this in Standard Form: 3 x2 − 7 + 4 x3 + x6 The highest degree is 6, so that goes first, then 3, 2 and then the constant last: x6 + 4 x3 + 3 x2 − 7 You don't have to use Standard Form, but it helps.
