The video tutorial explains how to find the zeros of a quadratic expression, specifically 6x squared minus 2x. It begins by setting the expression equal to zero and identifying a common factor. The expression is then factored into 2x and 3x minus 1. Each factor is set to zero to solve for the zeros, resulting in x equals 0 and x equals one-third. The tutorial concludes by summarizing the zeros found for the quadratic expression.
