Here is the beginning
I had to put this equation > 36x^2 - 100y^2 - 72x + 400y = 3928
in this form
With Help I got to this stage
36(x-1)^2 - 100(y-2)^2 = 3928 + 36 - 400
36(x-1)^2/99 - 100(y-2)^2/35.64 but the simple form has a^2 and b^2 and I cant find the square root of 99 and 35.64 which leads me to beleive that im wrong, please help.
