Tutor: Hi! I am now working on your question and you will soon see me writing on your drawing board.
Student: The equation is y=2xsquared-4x-1
Tutor: Did I write the equation correctly?
Student: Yes you did
Tutor: Okay
Student: How would you find the vertex in this equation?
Tutor: I'll show you how.
Student: Ok thank you
Student: No im not familiar with calculus
Tutor: Okay
Tutor: We'll follow a different method.
Student: Ok
Tutor: Any questions so far?
Student: Nope
Tutor: These are the two values of 'x' for which y is 0.
Tutor: Any questions so far?
Student: No
Tutor: That's because P is halfway between A and B.
Student: Yes
Tutor: So, that's the vertex of the given curve.
Student: Is there another way to solve this because my teacher taught us an easier and quicker way to do these problems.
Tutor: Okay
Student: This is how my teacher taught us
Tutor: Oh..Okay.
Tutor: Here, we have a =2 and b = -4.
Tutor: Any questions so far?
Student: No
Tutor: What's the value of 2(1)^2-4(1) -1?
Student: -3
Tutor: That's right.
Tutor: So, the vertex is (1,-3).
Student: Oh okay thanks. i have a test on this tomorrow so i wanted clarification thank you so much.
Tutor: Are there any more questions that I can help you with?
Student: Can you help me out on this probelm
Tutor: Sure go ahead.
Tutor: Type it on the board.
Student: Y=xsquared + 2x
Tutor: Do we have to find the vertex for this problem too?
Student: Yes pleas
Student: Please*
Student: So the other coordinate is -1
Tutor: Yes, you are too quick :)
Student: Thanks
Student: :)
Tutor: Any questions so far?
Tutor: Are there any more questions that I can help you with?
Student: No thats it thanks...bye
Tutor: Are there any more questions that I can help you with?

Student: No i understand them now thanks
Student: I have to go so bye
Tutor: Bye
Student: Thanks a lot
