12x^+2x^2=2y^2+28y-6

Hello,

There is no X intercept but there is a Y

Y intercept = (0,-7 + 2 square root of 13), (0,-7, - 2 square root 13)

Center (-7,0)

Vertices: (-7+√x2+52,0), (-7-√x2+52,0)

(-7+x2+52,0), (-7-x2+52,0)

Foci: (-

42-√42 (x2+52) 6,0), (-

42+√42 (x2+52)

6

,0)

(-42-42 (x2+52) 6,0), (-42+42 (x2+52) 6,0)

I honestly dont know what your trying to solve so im guessing thats what you wanted ...
