Question

Write the standard equation of each Ellipse. Find the center, vertices, co-vertices and foci. Show all work

1. 25x^2 + 9y^2 = 225

Answer 1

Medal Pleas :) Simplifying
9y2 + -25x2 = 225

Reorder the terms:
-25x2 + 9y2 = 225

Solving
-25x2 + 9y2 = 225

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-9y2' to each side of the equation.
-25x2 + 9y2 + -9y2 = 225 + -9y2

Combine like terms: 9y2 + -9y2 = 0
-25x2 + 0 = 225 + -9y2
-25x2 = 225 + -9y2

Divide each side by '-25'.
x2 = -9 + 0.36y2

Simplifying
x2 = -9 + 0.36y2

Reorder the terms:
9 + x2 + -0.36y2 = -9 + 0.36y2 + 9 + -0.36y2

Reorder the terms:
9 + x2 + -0.36y2 = -9 + 9 + 0.36y2 + -0.36y2

Combine like terms: -9 + 9 = 0
9 + x2 + -0.36y2 = 0 + 0.36y2 + -0.36y2
9 + x2 + -0.36y2 = 0.36y2 + -0.36y2

Combine like terms: 0.36y2 + -0.36y2 = 0.00
9 + x2 + -0.36y2 = 0.00
