Tutor: Hi! I am now working on your question and you will soon see me writing on your drawing board.
Tutor: Hello
Student: Hello
Student: Sorry its 3x ^3
Tutor: And the last one is x or x^2?
Student: X
Tutor: Ok
Tutor: Ok
Tutor: Here the powers of x with odd degree
Tutor: Is 2x^3
Tutor: And with even degree are 3x^2 and -1
Tutor: We see that 3 - 1 = 2
Tutor: That is
Tutor: The sum of the co eff of the powers of x with even degree = sum of the co eff of the powers of x with odd degree
Tutor: Hence x +1 is a factor
Tutor: Any questions so far?
Student: Nope
Tutor: Hence
Tutor: We haev
Tutor: X = 0
Tutor: Or x + 1 = 0
Tutor: Or 2x - 1 = 0
Tutor: Hence
Tutor: X = 0, -1 or 1/2
Tutor: That is the answer
Tutor: I hope I have been clear
Student: Ok thanks
