I will do the hard one, you do the easy one
144x^2 + 864x + .... - (25y^2 + 100y + ...) =2404
144(x^2 + 6x + ....) - 25(y^2 + 4y + ...) = 2404
144(x^2 + 6x + 9) - 25(y^2 + 4y + 4) = 2404 + 1296 - 100
144(x+3)2 - 25(y+2)^2 = 3600
divide each term by 3600
(x+3)^2 /25 - (y+2)^2 /144 = 1
do the 2nd one the same way
3455
