How do you solve dy/dx=(y−1)(y+1) if the solution passes through the point (x, y)=(4,0)(x, y)=(4,0)?

i got y=(1+e^(2x-8))/(1-e^(2x-8)) but it was wrong: (

Question part points submissions used suppose that 100 lottery tickets are given out in sequence to the first 100 guests to arrive at a party. of these 100 tickets, only 12 are winning tickets. the generalized pigeonhole principle guarantees that there must be a streak of at least l losing tickets in a row. find l.
