Hi,

I'm having trouble solving this equation.. I know it is supposed to turn out a quadratic equation, but I just can't do the math.. Would be incredibly grateful if anyone could help!!

Here it goes:

0,6 = √(Wa*0,4390)^2 + (Wb*0,8235)^2 + 2*(Wa*0,4390)*(Wb*0,8235)*0,253454

Now the squareroot is supposed to cover the entire right side of the equation. Wa and Wb are unknowns.
