Question 1058340: Given the following foci, write an equation for each ellipsis, in Standard
Form. The standard form is (x2/a2)+(y2/b2)=1.
foci= (square root of -45, 0) (square root of 45, 0) = (x2 / 81) + (y2/ 36) = 1

I think that's ok.
a%5E2-b%5E2=c%5E2
81-36=c%5E2
45=c%5E2
sqrt%2845%29=c
Yes it checks.
