Question

What are the three simple steps which will help you to decide whether the given terms are like or unlike?

Answer 1

Answer:

Like terms are the terms which have the same variables with same exponent for each variable.

Example :

7x, 3x, - 4x

Unlike terms are the terms which have same variables or different variables.

If they have same variables, the exponents will not be same.

Example :

9x2, 5xy, - 4xy2, y, 6

Answer 2

Three simple steps which will help you to decide whether the given terms are like or unlike

Explanation:

• When we look at algebraic terms to find like terms, first we ignore the coefficients and only look if terms have the same variables with same exponents.
• Those terms which qualify this condition are called like terms.

• The terms having the same variable with different exponents or different variable with same exponents are called Unlike terms.

Example:

1)$5x2y + 7xy2 -3xy - 4yx2$

• unlike terms

2) $a2 - 3b2 + 7b2 - 9a2 + 6ab + 5$

• Like terms = $a2 and - 9a2$

• Unlike terms = $a2and 6ab$
