A video that demonstrates one of the basic techniques involved in factorizing an equation that contains the difference of two terms which are also perfect squares themselves and are equated to 0. The solution to such type of problems is easy and simply involves factorizing one side using a basic algebraic formula (The formula is a^2 - b^2 = (a + b) (a - b) ). We will thus obtain two linear equations for the variable (in the form given above) which must be in turn, equated to zero. The final solutions for the variable can then simply be found by solving the linear equations so obtained.
