1. Let's clarify the problem: it seems you're asking whether to factorize first in the expression or equation involving 2.2. 2. Generally, when solving algebraic problems or simplifying expressions, factorization is often a helpful first step to simplify or solve the expression/equation. 3. However, if the expression is already simple or if factorization won't simplify the problem, sometimes it's better to proceed directly with other operations such as distribution or substitution. 4. For example, if you have an expression like $2.2(x + 3)$, you can either distribute first or factorize if possible. 5. In summary, factorize first when it simplifies solving or understanding the expression; otherwise, proceed with the most straightforward method. 6. If you have a specific expression or equation involving 2.2, please share it, and I can guide you whether to factorize first or not.
