Solve a quadratic by applying the square root method

The video tutorial explains how to solve the equation y = X^2 - 16 using two methods: factoring by the difference of squares and the square root method. Initially, it demonstrates factoring by setting the equation to zero and rewriting it as (X - 4)(X + 4) = 0, leading to solutions X = 4 and X = -4. The tutorial then introduces the square root method, which involves isolating X^2, adding 16 to both sides, and taking the square root to find X = ±4. Both methods yield the same solutions, highlighting the versatility of the square root method for equations in the form of AX^2 + C.
