Question

16x^2+25y^2-128x+200y+256

Answer 1

ellipse

Answer 2

yes there is a formula that u have to use. Do u have it by any chance?

Answer 3

ok so basically we have to change it into this form
(x - h)²/a² + (y - k)²/b² = 1

Answer 4

ok so what u do is lets gather the x and y terms
16x^2-128x+25y^2+200y+256

Answer 5

ok so now we have to complete the square for the x's and the y's and we move over the 256 to the other side and remember whatvr u do to one side u gotta do to the other
16(x^2-8x+16)+25(y^2+8x+16)=-256+16*16+25*16

Answer 6

Did u follow so far?
