I want to solve this equation for x:
ax^2+cx^(1.5)=b
But this is not as easy as it seemed. Perhaps someone can help.

Thank you!
But now I need to find the roots of this 4th degree polynomial.. Does anyone know a method with not too much computational load? The polynomial looks like this:
$\displaystyle au^4+cu^3-b$
Where:
$\displaystyle \sqrt{x}=u$
in:
$\displaystyle ax^2+cx\sqrt{x}-b$

There is a method called Ferrari's method but maybe a little bit difficult
Méthode de Ferrari - Wikipédia
Sorry for the French version, I could not find the English one
Anyway mathematics are a universal language !
