**C**annot calculate the second derivative to to find the region where the function is concave or convex

f(x) = (1+2x)/(2+x^2)
Question: Compute the second derivative and use it to find the region where f(x) is concave and where is convex.
f''(x) = (4x^3 + 6x^2 - 24x - 4)/(x^2 + 2)^3 I cant find x to f''(x) = 0 so I cant find the region where f(x) is concave or convex.
Can anyone help me please??
