Answer 2

Given Equation is 5x^2 + 3y^2 - 4z^2  --------- (1)

Given Equation is -13y^2 + 3z^2 - x^2 --------- (2).


On Subtracting both equations, we get

(-13y^2 + 3z^2 - x^2) - (5x^2 + 3y^2 - 4z^2)

-13y^2 + 3z^2 - x^2 - 5x^2 - 3y^2 + 4z^2

-x^2 - 5x^2 -13y^2 - 3y^2 + 4z^2 + 3z^2

-6x^2 - 16y^2 + 7z^2.


Hope this helps!
