For 1The first 4 attached questions do not make sense to me. The 'correct' answers are dotted but I'd like to see the proof for it. (They are user-generated problems from the Sparknotes website so I anticipated some errors in them. I can't tell whether or not I'm wrong or the problem had wrong answer choices)
Status problem 1:Unsolved
Status problem 2:Unsolved
Status problem 3:Unsolved
Status problem 4:Unsolved
Also, the forumula is used to solve polynomials correct? Polynomials and or Binomials?
