ODE solution for a simple case

I was trying to solve this but I can't not fix the problem :( please help me.

a,b,f and d positive vale.

Clear["Global*"]
eqns = a*y'[t] == b*y[t]^2 + f*y[t]+d;
DSolve[{eqns, y[0] == 0, y[t0] == 1}, y[t], t]
y[t] = x'[t]/x[t];
DSolve[{eqns, x[t0] = x0}, x[t], t]

• First DSolve : You use 2 initial conditions, one is enough for an ode of first order. t0 isn't defined! Is y[t] = x'[t]/x[t]intended to transform the ode? Jan 14 at 14:53
• Okay how can put two initial conditions? t0 is positive and I just want the solution with t0. I would like to use the soluion of y[t] from first DSolve and put to another Dsolve Jan 14 at 14:59
• That means: Your 2nd ode is y[t]==x'[t]/x[t]? Jan 14 at 15:03

sol=DSolve[{a*y'[t] == b*y[t]^2 + f*y[t]+ d,
