Defensible Pedagogical Basis:

Specification Grid Section 5 (Computational Methods): Root finding by Newton-Raphson method is explicitly mandatory under CDC Grade 11 Mathematics.

Approach Summary: Use tangent line slope or Taylor series expansion f(x_n + h) ≈ f(x_n) + h f'(x_n) = 0 to obtain h = -f(x_n)/f'(x_n). Iterate for x³ - 2x - 5 = 0 until |x_{n+1} - x_n| < 0.0005.
