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....

**** 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
