(F)=3F^2+5F-1/F+2(1)=-8
We move all terms to the left:
(F)-(3F^2+5F-1/F+2(1))=0
Domain of the equation: F+21)!=0We get rid of parentheses
F∈R
-3F^2+F-5F+1/F-21=0
We multiply all the terms by the denominator
-3F^2*F+F*F-5F*F-21*F+1=0
We add all the numbers together, and all the variables
-3F^2*F-21F+F*F-5F*F+1=0
Wy multiply elements
-3F^3+F^2-5F^2-21F+1=0
We do not support eFpression: F^3
