Quadratic Equation

[Ryan]

Does anyone know what would be the most efficient way to
solve a quadratic equation, by either using solver or not?

=(-B1+((B1^2)-(4*A1*C1)))/(2*A1)

and

=(-B1-((B1^2)-(4*A1*C1)))/(2*A1)

where A1, B1 and C1 contain the respective coefficients.

Looks like you forgot the sqrt !

(-B + sqrt(B^2-4AC)) /2A
&
(-B - sqrt(B^2-4AC)) /2A
