WebbWe know that we must follow the order of operations to simplify expressions with square roots. The radical is a grouping symbol, so we work inside the radical first. We simplify in this way: So if we have to add , we must not combine them into one radical. Trying to add square roots with different radicands is like trying to add unlike terms. Webb5 apr. 2024 · Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division. The given expression is 2 (x - 3) + 7 (x + 2). The expression will be simplified as below, Therefore, the correct option is C. The expression will be E = 9x + 8.
