Tolongg penyelesaiannyaa

menurut saya jawabannya d.

#maaf kalau salah

-(x^2 - 2nx + n^2)/4 + (y^2 - 4my + 4m^2)/9 = 1
- (x - n)^2 / 4 + (y - 2m)^2 / 9 = 1

Persamaan Asimtot
- (x - n)^2 / 4 + (y - 2m)^2 / 9 = 0
(y - 2m)^2 / 9 = (x - n)^2 / 4
(y - 2m)^2 = 9/4 (x - n)^2
y - 2m = ± 3/2 (x - n)
2y - 4m = ± 3(x - n)
Memotong sumbu x jika y = 0
2(0) - 4m = ± 3(x - n)
-4m = ± 3(x - n)

1) -4m = 3(x - n)
-4m = 3x - 3n
3n - 4m = 3x
x = (3n - 4m)/3

2) -4m = -3(x - n)
-4m = -3x + 3n
3x = 4m + 3n
x = (4m + 3n)/3

Jarak = x2 - x1 = (4m + 3n)/3 - (3n - 4m)/3
= (4m + 3n - 3n + 4m)/3
= 8m/3
