4x^2+8x+3y^2+6y-17=0

4 x^{2} + 8 x + 3 y^{2} + 6 y - 17 = 0

(h, k) = (- 1, - 1), a = 6, b = 22

Solution steps

4 x^{2} + 8 x + 3 y^{2} + 6 y - 17 = 0

Rewrite

4 x^{2} + 8 x + 3 y^{2} + 6 y - 17 = 0

in the form of the standard ellipse equation

\frac{( x - ( - 1 ) ) ^{2}}{( 6 ) ^{2}} + \frac{( y - ( - 1 ) ) ^{2}}{( 2 2 ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 1, - 1), a = 6, b = 22

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (- 1, - 1), b = 22, a = 6
