Indicial Equations: Quadratic Form & Simultaneous Equations

This lesson explains how to apply the laws of indices to solve more advanced problems: indicial equations that reduce to a quadratic equation, and simultaneous equations involving two unknowns in the index. You’ll learn how to use substitution (letting y = aˣ) to turn an exponential equation into a familiar quadratic that can be factorized, and how to equate indices in simultaneous equations to form and solve linear equations for two unknowns. Clear step-by-step worked examples make each method easy to follow.

Perfect for students preparing for WAEC, NECO, and JAMB Mathematics.
