4x^2+6y^2-8x+4y-6>= 0

4 x^{2} + 6 y^{2} - 8 x + 4 y - 6 \geq 0

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

Solution steps

4 x^{2} + 6 y^{2} - 8 x + 4 y - 6 \geq 0

Rewrite

4 x^{2} + 6 y^{2} - 8 x + 4 y - 6 \geq 0

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

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

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

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