x^{(2)}+4x+4y^{(2)}-6y+9=3

x^{(2)} + 4 x + 4 y^{(2)} - 6 y + 9 = 3

(h, k) = (- 2, \frac{3}{4}), a = \frac{1}{2}, b = \frac{1}{4}

Solution steps

x^{2} + 4 x + 4 y^{2} - 6 y + 9 = 3

Rewrite

x^{2} + 4 x + 4 y^{2} - 6 y + 9 = 3

in the form of the standard ellipse equation

\frac{( x - ( - 2 ) ) ^{2}}{( \frac{1}{2} ) ^{2}} + \frac{( y - \frac{3}{4} ) ^{2}}{( \frac{1}{4} ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 2, \frac{3}{4}), a = \frac{1}{2}, b = \frac{1}{4}

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (- 2, \frac{3}{4}), a = \frac{1}{2}, b = \frac{1}{4}
