# Addition of polynomials

**Addition of polinomials **

Adding polynomials is essentially combining like terms of polynomial expressions. When adding polynomials, they can either be arranged vertically or grouped according to degree.

Add
P(x)= 2p

^{3} + 6p

^{2} +9p to Q(x) = 3p

^{3} - 8p

^{2}
- 11p

The resulting polynomial is: P(x) + Q(x)=
5p

^{3} - 2p

^{2} - 2p

Let's see the combinations of like terms:

2p

^{3} + 3p

^{3 } = 5p

^{3}
6p

^{2} - 8p

^{2 } = -2p

^{2}
9p - 11p = -2p
