This is the real solution, btw:
Say x = 10
We write : x(x+3)(x+6)(x+9) + 81
Rewrite to: x(x+9) × (x+3)(x+6) + 81
Equals: (x^2 + 9x) × (x^2 + 9x + 18) + 81
Now substitute y for x^2 + 9x
We have: y × (y+18) + 81
Simplify: y^2 + 18y + 81
Which is equal to (y+9)^2
Get the square root and you have y+9
Equal to x^2 + 9x + 9
X=10 so
100 + 90 + 9
