172n=180(n-2)/n
We move all terms to the left:
172n-(180(n-2)/n)=0
Domain of the equation: n)!=0We multiply all the terms by the denominator
n!=0/1
n!=0
n∈R
172n*n)-(180(n-2)=0
Wy multiply elements
172n^2=0
a = 172; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·172·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
