Proof by induction: 1) Check it for x=0: f₀²=1=f₀f₁. ✓ 2) Assume that it's true for some n∈ℕ, i.e. f₀²+f₁²+...+fₙ²=fₙfₙ₊₁. 3) Prove it for n+1 (using the assumption made in step 2): f₀²+f₁²+...+fₙ²+fₙ₊₁²=fₙfₙ₊₁+fₙ₊₁²=(fₙ+fₙ₊₁)fₙ₊₁=fₙ₊₂fₙ₊₁.

This identity is a “made-up”, surely, as much as our entire logic system is a made-up.
