Center: ( [ Select ] [\"1\", \"-3\", \"3\", \"-1\"] , [ Select ] [\"-1\", \"3\", \"1\", \"-3\"] )
Orientation: [ Select ] [\"Vertical\", \"Horizontal\"]
Solution
7x^2 + 5y^2-14x+30y-18=0
7(x^2 -2x) +5(y^2 +6y) -18=0
7((x-1)^2 -1) +5((y+3)^2 -9)-18=0
7(x-1)^2 -7 +5(y+3)^2 - 45-18=0
7(x-1)^2 +5(y+3)^2 -70=0
dividing both sides by 70
(x-1)^2/10 + (y+3)^2/14=1
Therefore centre is (1,-3)
Here a^2<b^2
And in such case the orientation is vertical
a^2=14
b^2=10
c^2= a^2-b^2=14-10=4
