Lecture no. 13 from the course: Algebra II
Taught by Professor James A. Sellers | 31 min | Categories: The Great Courses Plus Online Mathematics Courses
The square root approach to solving quadratic equations works not just for perfect squares, such as 3 × 3 = 9, but also for values that don't seem to involve squares at all. Probe the idea behind this technique, and also venture into the strange world of complex numbers.
