In the expression 4x + 6x, what type of terms are 4x and 6x?

In the expression 4x + 6x, both terms, 4x and 6x, are referred to as like terms. This classification occurs because like terms share the same variable raised to the same power. Here, both terms have the variable x raised to the first power, making them compatible for addition or subtraction. Thus, they can be combined to yield a single term, which in this case would result in 10x when added together. Understanding the concept of like terms is essential in algebra as it facilitates simplification and manipulation of expressions.
