Solving a rational Equation

The video tutorial explains the process of solving equations using cross multiplication. It begins with setting up the cross multiplication, followed by performing the multiplication and ensuring the equation is maintained. The tutorial also covers determining the least common denominator (LCD) and explains that it is equivalent to cross multiplication. The process of factoring and solving the equation is demonstrated, leading to the solution of the equation by taking the square root of both sides. The tutorial concludes by discussing the nature of the solution, highlighting that it is irrational and includes both positive and negative values.
