Notice that if the c term is missing, you can always factor x from the other terms. We therefore use the theorem from the previous section. When you encounter an incomplete quadratic with c - 0 (third term missing), it can still be solved by factoring.

If, when an equation is placed in standard form ax 2 + bx + c = 0, either b = 0 or c = 0, the equation is an incomplete quadratic.ĥx 2 - 10 = 0 is an incomplete quadratic, since the middle term is missing and therefore b = 0.

Place a quadratic equation in standard form.Upon completing this section you should be able to: QUADRATICS SOLVED BY FACTORING OBJECTIVES You now have the necessary skills to solve equations of the second degree, which are known as quadratic equations. In previous chapters we have solved equations of the first degree. All skills learned lead eventually to the ability to solve equations and simplify the solutions. Solving equations is the central theme of algebra.
