Find the foci of the ellipse whose equation is x^2/16+y^2/36=1

  (0, ±2√5)

Step-by-step explanation:

The foci are the points on the major axis that are the length of the semimajor axis away from the co-vertices.

Here, that means their y-coordinate is ±√(36-16) = ±√20 = ±2√5.

The x-coordinate is that of the major axis, x=0.
