The video tutorial covers the factorization of quadratic equations, starting with the basic form of a quadratic equation, AX^2 + BX + C. It explains the sum of product rule for finding values that multiply to C and add to B. The tutorial also addresses cases where A is not equal to 1, requiring different bracket combinations. Finally, it introduces the concept of the difference of two squares, showing how to factor expressions like X^2 - 81 using square numbers.
