help me Use the Quadratic Formula to solve N2=6n

n^2 = n.
n^2  n = 0,
n = (b+sqrt(b^24ac)) / 2a.
n = (1+sqrt(14*1*0)0 / 2,
n = (1+sqrt(10)) / 2,
n = (1+1) / 2,
n = (1+1) / 2 = 1.
n = (11) / 2 = 0/2 = 0.
Solution set: n = 1, and 0.

Correction:
n^2 = 6n.
n^2  6n = 0,
n = (6 + sqrt(364*1*0)) / 2,
n = (6 + sqrt(360)) / 2,
n = (6 +sqrt(36)) / 2,
n = (6 + 6) / 2,
n = (6+6) / 2 = 6.
n = (66) / 2 = 0/6 = 0.
Solution set: n = 6, and 0.

n^2= 6n
n^26n=0
n(n6)=0
n=0,6
