3x^2+y^2+12x-2y+1=0

3 x^{2} + y^{2} + 12 x - 2 y + 1 = 0

(h, k) = (- 2, 1), a = 2, b = 23

Solution steps

3 x^{2} + y^{2} + 12 x - 2 y + 1 = 0

Rewrite

3 x^{2} + y^{2} + 12 x - 2 y + 1 = 0

in the form of the standard ellipse equation

\frac{( x - ( - 2 ) ) ^{2}}{2 ^{2}} + \frac{( y - 1 ) ^{2}}{( 2 3 ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 2, 1), a = 2, b = 23

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (- 2, 1), b = 23, a = 2

36 x^{2} + 9 y^{2} + 288 x - 90 y + 477 = 0

(\frac{x ^{2}}{72}) + (\frac{y ^{2}}{21}) = 1

16 x^{2} + 25 y^{2} = 1400

5 x^{2} + 9 y^{2} - 80 x + 54 y + 221 = 0

25 x^{2} + 16 y^{2} + 100 x - 96 y - 154 = 0
