Remember that the terms of a polynomial are the parts of the polynomial separating by addition and subtraction; in other words, the parts separated by (+) and (-) signs. Knowing this, we can separate the terms of our polynomial:

- First term:

- Second term:

- Third term:

- Fourth term:

- Fifth term:

We can conclude that there are
5 terms in the polynomial
