X-1 x30 x 1x 3 0. 4 examples and their solutions. In order to solve the quadratic equation ax 2 bx c 0 by factorization the following steps are used.
To skip to the shortcut trick go to time 611.
Use a factoring strategies to factor the problem. Xx - 3 0 Then either x or x - 3 is 0. Now if this is the first time that youve seen this type of whats essentially a quadratic equation you might be tempted to try to solve for s using traditional algebraic means but the best way to solve this especially when its explicitly equal to 0 is to factor the left-hand side and then think about the fact that those binomials that you factor into that they have to be equal to 0. From the example above the quadratic problem simply reduces to a linear problem which can be solved by simple factorization.
