Like terms are terms in a formula or expression that have the same variables raised to the same powers. In other words, like terms have identical variables with the same exponents.

To identify like terms in a formula, you need to look at the variables and their corresponding exponents. For example, let's consider the expression:

2x^2 + 3y - 4x^2 - 5y + 7z

In this expression, the like terms would be the ones that have the same variables raised to the same powers. So, the like terms in this expression are:

2x^2 and -4x^2 (both have x raised to the power of 2)
3y and -5y (both have y raised to the power of 1)

On the other hand, 7z is not a like term to any other term because it has a different variable (z) compared to the other terms in the expression.

By identifying like terms, you can combine them by adding or subtracting their coefficients. In this example, you could combine the like terms to simplify the expression to:

-2x^2 - 2y + 7z
