How to approach this problem. I tried to make a eq like x^2 - 8x + 15, but it does not lead me anywhere. Any other ideas?

A function got f(x) = 3 , 5 as one of the solutions
Now they ask possible solution for f(x+2).
(x+2) = 3 ---->Eq1
(x+2) = 5 ---->Eq2
From Eq 1 and 2, possible solutions are
x = 1 , 3
