Hello !

Yesterday I had to solve the following equation :
(-3+i)x²+(5i-1)x+2=0
I tried it with the csolve fucntion and all I got was an approximation. I
thus tried to use the well known quadratic formula within a function
(-b+/-sqr(b²-4ac)/2a) and I got the exact answer. How is that possible ?
Doesn't the 92 use this formula to solve that kind of equation ?
Anyway, I'd like to write a function that would extract the a,b and c from
a quadratic equation and display the solutions as a list but I can't figure
how to extract the coefs. Has anyone an idea ?

TIA

Alexis
