Review the foundation notes with TTA Pro Mr.O before solving. If this skill drill is part of an anchor lesson, the notes stay available during practice.

Objective: By the end of this lesson you can solve any Digital SAT quadratic equation in one variable: reading roots off a factored form at Level 1, factoring and using the square-root property at Level 2, applying the quadratic formula and Vieta's sum and product rules at Level 3, switching between an equation, a table, a graph and a story at Level 4, handling parameters, radical equations and answer-form traps at Level 5, and at Level 6 pinning an unknown constant with a condition such as 'exactly one real solution' inside two minutes.
