The question I'm trying to solve is part (ii) of the attached file(adsbygoogle = window.adsbygoogle || []).push({});

I've used partial derivatives to input back into the Black Scholes equations and after factorising it, I've got it down to:

(a + 2bt + αt +r) * (S².c.e^(at+bt²) = 0

I'm now stuck on what to do next, as there would need to be 2 equations in order to solve simultaneously which isn't the case above.

Help would appreciated
