5(x+1)^2+3y^2=15

5 (x + 1)^{2} + 3 y^{2} = 15

(h, k) = (- 1, 0), a = 3, b = 5

Solution steps

5 (x + 1)^{2} + 3 y^{2} = 15

Rewrite

5 (x + 1)^{2} + 3 y^{2} = 15

in the form of the standard ellipse equation

\frac{( x - ( - 1 ) ) ^{2}}{( 3 ) ^{2}} + \frac{( y - 0 ) ^{2}}{( 5 ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 1, 0), a = 3, b = 5

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (- 1, 0), b = 5, a = 3
