No need to fear I'll help you get through this problem :D

Okay so this is the original problem, let's work down from it....

(3x² + 5x - 8) + (5x² - 13x - 5)

**** Remember we need to add only the values that have like variables of the same exponents ****

(8x² - 8x - 13)   <-----    this will be the answer you will get when you add the values together....

I hope this helps you understand this problem! :D
