2x^2+3y^2+8x+8y-10=0

2 x^{2} + 3 y^{2} + 8 x + 8 y - 10 = 0

(h, k) = (- 2, - \frac{4}{3}), a = \frac{35}{3}, b = \frac{70}{3}

Solution steps

2 x^{2} + 3 y^{2} + 8 x + 8 y - 10 = 0

Rewrite

2 x^{2} + 3 y^{2} + 8 x + 8 y - 10 = 0

in the form of the standard ellipse equation

\frac{( x - ( - 2 ) ) ^{2}}{( \frac{35}{3} ) ^{2}} + \frac{( y - ( - \frac{4}{3} ) ) ^{2}}{( \frac{70}{3} ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 2, - \frac{4}{3}), a = \frac{35}{3}, b = \frac{70}{3}

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (- 2, - \frac{4}{3}), a = \frac{35}{3}, b = \frac{70}{3}

\frac{2 - x ^{2} - y ^{2}}{x ^{2} + y ^{2} - 9} > 0

f (x) = x^{2} + 3 f (x) (f (x))

x^{2} + 4 y^{2} - 6 x - 8 y + 9 = 0

16 x^{2} + 36 y^{2} = 49

\frac{( x + 1.23 ) ^{2}}{1.5 9 ^{2}} + \frac{y ^{2}}{1.0 1 ^{2}} = 1
