Answer 2

It appears that the expression you provided is incomplete and contains some formatting issues. The caret symbol (^) is typically used to represent exponentiation in mathematical notation, but it seems to be misplaced in the expression. Additionally, there is no equal sign before the constant term "11".

To help you further, could you please clarify the expression and correct any formatting errors? For example, if the expression is intended to be a polynomial equation, please provide it in the correct format.
