Class 7 Maths Algebraic Expressions Like and Unlike Terms

Like and Unlike Terms

Like terms are terms that have the same variables and powers. The coefficients do not need to match.

Ex: 8xy2 and −5xy2 are like terms because they have the same variables and power.

Unlike terms are terms that have not the same variables or powers.

Ex: 3abc and 3xyz are unlike terms because they have different variables.

Problem: Identify like terms in the following:

-xy2, -4yx2, 8x2, 2xy2, 7y, -11x2, -100x, -11yx, 20x2 y, -6x2, y, 2xy, 3x

Solution:

Like terms are:

(i) –xy2, 2xy2                     (ii) -4yx2, 20x2 y                     (iii) 8x2, -11x2, -6x2                       (iv) 7y, y  

(v) -100x, 3x                     (vi) -11yx, 2xy
