Equation into Excel using PEMDAS

A12=(-(g^2)/(3*Pmax)) - ((-(g^4*hpo^4)-12*g*hpo^3*Pmax^2)/(3*hpo^2*Pmax*Z(Pmax,hpo))) - (Z(Pmax,hpo)/(3*hpo^2*Pmax)) where I have Z(Pmax,hpo) referencing the cell with the formula you gave

Z(Pmax,hpo) is in cell B1

A12 = (-(H4^2)/(3*K8)-((-(H4^4*G4^4)-12*H4*G4^3*K8^2)/(3*G4^2*K8*N8)))-(N8)/(3*G4^2*K8)

Z (Which is in cell N8) = (-(H4^6)*G4^6-18*H4^3*K8^2-54*G4^4*K8^4+6*SQRT(3)*SQRT(2*H4^3*G4^9*K8^6+27*G4^8*K8^8))^(1/3)

Everything else look correct to me.
