x^2+4y^2+4x-8y-8 = 0
\n" ); document.write( "(x-2)^2-4 + 4(y-1)^2 -4 -8 = 0
\n" ); document.write( "(x-2)^2 + 4(y-1)^2 = 16
\n" ); document.write( "(x-2)^2/16 + (y-1)^2/4 = 1 Ellipse C(2,1) major axis along y = 1
\n" ); document.write( " Standard Form of an Equation of an Ellipse is \"%28x-h%29%5E2%2Fa%5E2+%2B+%28y-k%29%5E2%2Fb%5E2+=+1+\"
