This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - To memorize the quadratic formula, x = (−b ± √(b²−4ac)) / 2a, as it is essential and not provided on the AFOQT Math Knowledge subtest. - How to use the formula to solve any quadratic equation in the form ax² + bx + c = 0, especially when factoring is not obvious. - That the discriminant, b²−4ac, is a shortcut to determine the number of real solutions without fully solving the equation. - That a positive discriminant means two real solutions, a zero discriminant means one real solution, and a negative discriminant means no real solutions. - To watch for common AFOQT traps like equations not in standard form and sign errors when calculating the discriminant or formula.
