Example of adding of similar monomials.

Add the following monomials

4x3 + 3x3 + 2x2

Solution.

Are all these three terms similar monomials? No, they are not.

Only the two monomials 4x3 and 3x3 are similar monomials.

The coefficients of the similar monomials are 4 and 3.

4x3 + 3x3 + 2x2 =
7x3 + 2x2

The answer: 7x3 + 2x2.
