Hello, I have the basics of solving for foci, vertices, eccentricity and graphing ellipses down, but for some reason these two problems have me scratching my head.

x^2+4y^2=1 and y^2=1-2x^2 both of these need to be put into std form which is (x^2\a^2)+(y^2\b^2)=1, before I can solve for anything. Help!
