5x^2+20x+7y^2+14y=8

Lösung

5 x^{2} + 20 x + 7 y^{2} + 14 y = 8

Lösung

(h, k) = (- 2, - 1), a = 7, b = 5

Schritte zur Lösung

5 x^{2} + 20 x + 7 y^{2} + 14 y = 8

Rewrite

5 x^{2} + 20 x + 7 y^{2} + 14 y = 8

in the form of the standard ellipse equation

\frac{( x - ( - 2 ) ) ^{2}}{( 7 ) ^{2}} + \frac{( y - ( - 1 ) ) ^{2}}{( 5 ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 2, - 1), a = 7, b = 5

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (- 2, - 1), a = 7, b = 5

((x^2)/4)+((y^2)/(16))=1

(\frac{x ^{2}}{4}) + (\frac{y ^{2}}{16}) = 1

solvefor x,(Y(x)^2)/(4-x^2)=1

so l v e f or x, \frac{Y ( x ) ^{2}}{4 - x ^{2}} = 1

(y^2}{16}=1-\frac{x^2)/9

\frac{y ^{2}}{16} = 1 - \frac{x ^{2}}{9}

4 x^{2} + 9 y^{2} + 16 x - 36 y + 16 = 0

-16-x^2-y^2>= 0

- 16 - x^{2} - y^{2} \geq 0
