Question

How many terms are in a^2-ab+8b+b^2-1

Answer 1

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:
$a^2-ab+8b+b^2-1$
- First term: $a^2$
- Second term: $-ab$
- Third term: $8b$
- Fourth term: $b^2$
- Fifth term: $-1$

We can conclude that there are 5 terms in the polynomial $a^2-ab+8b+b^2-1$.
