Solve Quadratic Equations Using Factoring and the Quadratic Formulas

This video is about solving quadratic equations using the method of factoring and also the quadratic formulas. Three examples are presented: Example 1 - the equation (x-1)(x+8) = 0 is in a factored form already and therefore solved in a few steps. Example 2 - the equation x(x - 1) = 1 is expanded and because it cannot be factored, is solved using the quadratic formulas that are reviewed in the video. Example 3: the equation 2x^2 + 6 x = 8 is first simplified by dividing all terms by 2 since all coefficients and the constant even numbers, written in standard form, factored and then solved.
