Problems with polynomial equation

Hi, I have to program polynomial equation with sum of the multiplicand products.

you can see it here ((z^2)-z*((z1+z2)+((Q1+Q2)/A))+((z1*z2)+((Q1*z2)/A)+((Q2*z1)/A))==0)

where I do not have a value for z, z1 and z2 these suppose to be the output from this equation. the values of Q1, Q2 and A is known.

Would you please help me with that, I really do not know how to do it

Kind regards

"Equations" do not have an output. What is your actual question?

You have one equation and three unknowns. There will be an infinite number of solutions (unless there are severe constraints on the values.)
