Primitive of $\dfrac 1 {a x^2 + b x + c}$: Also presented as
In some older works, this result can also be seen presented as:
- $\ds \int \frac {\d x} {a x^2 + 2 b x + c}$
where the solution is then developed via the form:
- $\ds \dfrac 1 a \int \frac {\d x} {\paren {x + \frac b a}^2 + \paren {\frac c a - \frac {b^2} {a^2} } }$
