In this section we will discuss about like and unlike terms in solving algebraic expressions.
Like terms : The terms having the same literal (variable) with same exponents are called Like terms.
Example: 1) 12x and -5x 2) 4x 2 and ½ x 2
Unlike terms : The terms having the same variable with different exponents or different variable with same exponents are called Unlike terms .
Example : 1) 5x and 5y 2) 2x 2 and 3y 2
Some more examples :
1)In the algebraic expression 5x 2 y + 7xy 2 -3xy – 4yx 2
Like terms 5x2y and – 4yx2
Unlike terms 7xy2 and -3xy
2)In the algebraic expression a 2 - 3b 2 + 7b 2 - 9a 2 + 6ab + 5
Like terms Unlike terms
a2 and - 9a2 a2and 6ab
- 3b2 and 7b2 7b2
