Question

How can I combine like terms ?

Answer 1

Step-by-step explanation: To understand how to combine like terms, let's look at an example.

9c + 2c

The two parts of this expression, +9c and +2c, are called terms. The numbers in front of the variables, +9 and +2, are called coefficients.

Since the variables, c and c, are identical, the two terms in this problem are called like terms.

Like terms can be added together by simply adding their coefficients.

So in this problem, since 9 + 2 = 11, 9c + 2c is simply 11c.

Answer 2

examples: 7x + 3x = 10x

example: 10x^2 + 10x ^2 + 5 + 15 = 20x ^2 + 20
