Topic : Identity the variables, terms, numbers of in the following expressions.

Here, 14xy-7y-12yx+5y-10 is a algebraic expression.

We need to find out total number of terms. Answer : 5 terms. 1. 14xy, 2.-7y, 3.-12yx, 4.5y, 5.-10

then we need to find like terms. Answer : 14xy and - 12yx are like terms. (Because they have the same variable of xy), -7y and 5y are another like terms.

then we need to find unlike terms. Answer: 14xy, 7y, -10. Because they do not have same variables, thus it is called unlike terms.
