LIKE TERMS:-

• The terms having the same variable factors are called similar or like terms like terms may differ in their numerical coefficient.

For eg.

If the expression 3xy - 4xb+ 5yx + 7, the factors of 3xy are 3, x and y. The factors of 5yx and 5, x and y.

Thus, their algebraic factors(variable) are same.

Therefore, 3xy and 5xy are like terms.

UNLIKE TERMS:-

• The terms not having same variable factor are called unlike terms.

Example : In the expression 3xy - 4x + 5yx +7, 3xy and - 4x have different algebraic factors.

Similarly, 5yx and 7 have different algebraic factors.

• Hence, 3xy and -4x are unlike terms. 5yx and 7 are also unlike terms.
