**Polynomials are expressions such as 4x³+2x²+9x+4.**

**Adding Polynomials is a very simple concept**

**as long as you know the rules to adding them.**

**A typical Polynomial Addition Problem would look something like:**

**(2x²+3x+7) + (6x²+10x+1) = ?**

**When you add Polynomial equations**

**you can only add the numbers together**

**that have the same variables after the number.**

**For example, you could not add ****5x²****
and ****4x ****together.**

**BUT… you could add ****5x²**** and ****4x² ****together.**

**So, in the problem a few lines up, you could only add the ****2x²**** to the ****6x²**

**and only the ****3x**** to the ****10x**

**and only the ****7**** to the ****1****,**

**because they all have the same signs following the number.**

**So, the answer to the problem would be ****(8x²+13x+8).**

**This concept is called the adding of "like terms."**

**Follow that simple rule and adding polynomials is very easy.**
