To find like terms in algebraic expressions, it’s helpful to know that like terms have the same variable parts and the same powers. Let's break it down simply:

1. Find the Variables: First, look at the expression and identify the variables. For example, in the expression $3x^2 + 4x + 5 - 2x^2$, the variables are $x^2$ and $x$.

2. Look at the Coefficients: Like terms have to have the same variable part. In our example, $3x^2$ and $-2x^2$ are like terms because they both have $x^2$. The term $4x$ is different because it only has $x$.

3. Let’s Break It Down:

   • The terms are: $3x^2$, $4x$, $-2x^2$, and $5$.
   • The like terms are: $3x^2$ and $-2x^2$. The terms $4x$ and $5$ are not like terms because they are different.

When we combine like terms, we can simplify the expression to $x^2 + 4x + 5$.

Remember, combining like terms makes working with algebra easier!
