The video tutorial explains how to write a quadratic equation given specific roots. It begins by introducing the concept of quadratic equations and their standard form. The tutorial then demonstrates how to apply the quadratic formula using the given roots, 2 plus the square root of 3 and 2 minus the square root of 3. The process involves simplifying the equation by combining like terms and multiplying conjugates to find the product of the roots. Finally, the tutorial derives the quadratic equation x squared minus 4x plus 1 equals 0, which has the specified roots.
