Okay so I have this calculus teacher who is crazy and gave us this problem on an exam. I don't know how to figure it out and I tried getting explanations but they were really hard and complicated. So here is the problem(adsbygoogle = window.adsbygoogle || []).push({});

x^2 [f(x)]^4 + xf(x) = 6

f(2) = 1 Find f''(2)

I would most greatly appreciate it if someone showed me how to solve the problem step by step.
