Solving by Completing the square by factoring out a negative one

The video tutorial explains how to complete the square to find X intercepts. It begins with isolating terms to form a perfect square trinomial, factoring out coefficients, and adjusting the trinomial. The process involves dividing the middle term by two, squaring it, and adding/subtracting it within the trinomial. The tutorial highlights common mistakes, such as not factoring out negative coefficients. Finally, it demonstrates solving for X intercepts by taking the square root and adjusting the equation.
