3n*3n+3n*3n+3n*3n=3^439
We move all terms to the left:
3n*3n+3n*3n+3n*3n-(3^439)=0
We add all the numbers together, and all the variables
3n*3n+3n*3n+3n*3n+209-2.85910971967E=0
Wy multiply elements
9n^2+9n^2+9n^2+209-2.85910971967E=0
We add all the numbers together, and all the variables
27n^2+201.228134003=0
a = 27; b = 0; c = +201.228134003;
Δ = b2-4ac
Δ = 02-4·27·201.228134003
Δ = -21732.6384723
Delta is less than zero, so there is no solution for the equation
