If it is NOT factorable, then we can use one of the other methods as explained below. This method is applicable only when the quadratic expression is factorable. Thus, the solutions of the quadratic equation x 2 - 3x + 2 = 0 are 1 and 2. Step - 4: Solve each of the above equations.Įxample: Solve the quadratic equation x 2 - 3x + 2 = 0 by factoring it.įactoring the left side part, we get (x - 1) (x - 2) = 0.Step - 3: By zero product property, set each of the factors to zero.If you want to know how to factor a quadratic expression, click here. Step - 2: Factor the quadratic expression. ![]() i.e., Get all the terms of to one side (usually to left side) of the equation such that the other side is 0.
