This video tutorial explains how to perform synthetic division when the divisor is quadratic. It begins by discussing the limitations of synthetic division with linear denominators and introduces a workaround for quadratic divisors. The process involves factoring the quadratic into linear factors and performing synthetic division twice. The video provides detailed examples, demonstrating the algorithm and handling special cases like imaginary numbers. Finally, it shows how to write the results as polynomials, emphasizing the importance of using the quotient from the first division for the second round.
