The video tutorial explains how to solve quadratic equations by factoring using the bottoms up method. It begins with multiplying the coefficients a and c, then finding two numbers that multiply to the product and add to the middle term. The expression is factored, and each factor is divided by a. If division doesn't yield a whole number, the bottoms up method is applied. Finally, each factor is set to zero to solve for x, providing the solutions to the equation.
