First, solve the numerator $x^2 - 6x + 2 = 0$ using the quadratic formula: $$ x = \frac6 \pm \sqrt36 - 82 = \frac6 \pm \sqrt282 = 3 \pm \sqrt7 $$ Approximate values: $3 - \sqrt7 \approx 0.354$ and $3 + \sqrt7 \approx 5.646$.

Substitute this position vector back into the plane equation to solve for the scalar

: The algebraic expansion and simplification required in this paper mirror the exact mental endurance needed for the actual A-Level Paper 1 and Paper 2. First, solve the numerator $x^2 - 6x +

This was not a simple Gaussian elimination. NJC used a parametric variable ($\lambda$) in a 3x3 matrix.
