Hey guys,Have a question regarding expressing a quadratic surface in another form xpress the equation Q=x^2 + y^2 + 3z^2 + 2xy-2xz-2yz=4 in the form Q=a(x')^2 b(y')^2 c(z')^2=4.Not sure how to attempt, any help would be appreciated

Don't have a pic right now but they're correct. Which bit looks incorrect? I can double check

Q= x^2 y^2 3z^2 2xy-2xz-2yz = 4
The first term x^2 y^2 3z^2 2xy isnt a quadratic. Im assuming there are some operators missing?
It would be good to see a picture of the question.

Omg I'm so sorry!!! It should be x^2 + y^2 + 3z^2 + 2xy - 2xz - 2yz = 4 (I'll edit the original)

and the other one and what a(), b(), c() are and x', y', z' ...
Pls upload a pic of the question.

Are all the terms a, b, c in Q multiplied or added? What are they, ...
Pls^4 upload a pic of the question.
