[src]
y*(n + 2) + y*(n + 1) - 6*y*n = 0
$$- n 6 y + \left(y \left(n + 1\right) + y \left(n + 2\right)\right) = 0$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Divide both parts of the equation by (y*(1 + n) + y*(2 + n) - 6*n*y)/y
We get the answer: y = 0
y*(n+2)+y*(n+1)-6*y*(n) = 0
Expand brackets in the left part
yn+2+yn+1-6*yn = 0
Looking for similar summands in the left part:
y*(1 + n) + y*(2 + n) - 6*n*y = 0
Divide both parts of the equation by (y*(1 + n) + y*(2 + n) - 6*n*y)/y
y = 0 / ((y*(1 + n) + y*(2 + n) - 6*n*y)/y)
We get the answer: y = 0
