Write an equation of an ellipse in standard form with center at the origin and with the given characteristics.
Focus (8,0), x-int 12 with center at the origin.
Its standard form of equation: x%5E2%2Fa%5E2%2By%5E2%2Fb%5E2=1
a=12
a^2=144
c=8
c^2=64
c^2=a^2-b^2
b^2=a^2-c^2=144-64=80
equation: x%5E2%2F144%2By%5E2%2F80=1
