This Quartic Equation Has a Hidden Quadratic Inside 🔥

Can you solve x⁴ − 8x³ + 10x² + 24x + 5 = 0?
Most students try the rational root theorem first — wrong move.
The real trick: spot (x² − 4x) hiding twice inside the equation, complete the square, substitute y = x² − 4x, and it collapses into y² − 6y + 5 = 0.
A quartic solved like a quadratic. Four clean answers.
