## Quadratic Equations, Simultaneous Equations, and Inequalities

We go to great lengths at *Dominate the GMAT* to help you avoid doing difficult algebra on the GMAT. There are useful non-standard math techniques, for example, that can help you make variables your friend and turn otherwise problematic word problems into run-of-the-mill math problems.

Sometimes, however, solving algebra problems on the GMAT is simply unavoidable.

In this lesson you will specifically learn how to tackle three of the most commonly-tested “difficult” algebra concepts tested on the GMAT: **Quadratic equations**; **Simultaneous equations**; and **Inequalities**. But don’t worry — there won’t be a lot of long formulas to memorize (we still remember a song our 7th grade algebra teacher taught us to help us remember the Quadratic Formula, and don’t worry, we won’t be signing it to you here!); rather, we’ll focus on teaching you *how* the GMAT tests each of these topics and equip you with plenty of examples to illustrate everything you’ll need to master these GMAT algebra problem types.

**Specifically, this GMAT video tutorial covers:**

- Simultaneous equations, with multiple approaches and strategies so that you can choose the method that works best for you;
- GMAT quadratic equations, with an emphasis on the three most commonly-tested quadratic equations on the GMAT;
- The FOIL Method;
- How to factor quadratic equations, including the “reverse FOIL” method;
- Determining how many roots a quadratic equation has for determining sufficiency on GMAT Data Sufficiency questions;
- GMAT Inequalities;
- Numerous real GMAT practice problems with detailed answer explanations
