Write the equation in standard form

Question

36x^2 + 20y^2 - 720 = 0

Answer 1

36x^2 + 20 y^2 = 720

36x^/720 + 20y^2/720 = 1

x^2/20 + y^2/36 = 1

x^2/(sqr20)^2 + y^2/6^2 = 1

standard form is

x^2/a^2 + y^2/b^2 = 1

if a=b, it's a circle

if a does not equal b, it's an ellipse

this is an ellipse
