P + N =C + 2/C
solve for C
Please and thank you, I just want to make sure I got it right.
C*P + C*N = C^2 + 2
C^2 - (P + N)*C + 2 = 0, quadratic formula.
a = 1
b = - (P + N)
c = 2
C1 = ( - ( - (P + N) + sqrt(( - (P + N)^2 - 4*1*2)))/2 = P/2 + N/2 + (1/2)*sqrt(P^2 + 2*P*N + N^2 - 8)
C2 = P/2 + N/2 - (1/2)*sqrt(P^2 + 2*P*N + N^2 - 8)
C=1/2(P/NC)
