    Let's write the DE in general form as...

    \frac{dq}{dt} = a\cdot q^{2} + b = b\cdot (1+\frac{a}{b}\cdot q^{2}) (1)

    ... and it can be solved in standard fashion writing...

     \frac{dq}{1+ \frac{a}{b}\cdot q^{2}} = b\cdot dt (2)

    ... and then integrate both terms...

    Kind regards

    no, what'd be the fun with that? it makes no sense.

    do you believe is right by deleting each topic that is solved? (or if you solved by your own?) then people here would learn nothing, so in that case a math forum shouldn't exist.

    think again before deleting a question.
