y3 + 3y2y'x + 2x = 0, y' = - (y3 + 2x)/(3y2x)·; slope m at (2, 1): m = - (1 + 4)/3·122) = - 5/6
I think this answer right

I believe you got the statement of the problem wrong.
The point (2,1) does not lie on the curve y3x + x2x2 = 6.
One guess at possible correction would be the curve y3x + x2 = 6,
but its slope at (2,1) is -5/6.
