3x^2-14x-5 does not equal 3x^2+15x-5

anonymous · Answer

you can't just change a -14x for a 15x

E. Paul made a mistake and should go back to algebra I

anonymous · Answer

3x^2+15x-x-5**

anonymous · Answer

you sure its not 

3x^2-15x+x-5***

anonymous · Answer

Idk I notice some typos in the e2020 questions so that is possible

anonymous · Answer

well I was just confused because 15x-x = 14x.  if you want -14x you would need -15x+x

anonymous · Answer

Yeah I just guessed lol I don't have a freaking clue.
