Solution steps

One step at a time

(x−4)²+(y+2)²=25

Ellipse standard equation

(x−h)²a² +(y−k)²b² =1 is the ellipse standard equation
with center (h, k) and a, b are the semi-major and semi-minor axes

Rewrite (x−4)²+(y+2)²=25 in the form of the standard ellipse equation

(x−4)²5² +(y−(−2))²5² =1

Therefore ellipse properties are:

(h, k)=(4, −2), a=5, b=5

b>a therefore b is semi-major axis and a is semi-minor axis

Ellipse with center (h, k)=(4, −2), b=5, a=5
