Step-by-step explanation:
Given:

Step 1: 
Step 2:
Step 3: 
Now Solving for next steps we get
Step 4: 
dividing both side by 6 we get
Step 5:
And So the Final Answer is:
x = 3
I'm pretty sure it's Identity I hope it helps :)
Just let every x in f(x) be g(x)
it means:
f(g(x))=(2x^2+5)^2+(2x^2+5)+2
=4x^4+20x^2+25+2x^2+5+2
=4x^4+22x^2+32

oops, I accidentally messed this one up, so sorry
