With the variable as x and the a, b, and c the numbers in the quadratic equation

we can **find the value for x that will make the above equation true** by using this formula:

**Solve the equation below.** Do you see the *right side is 0*? **One side must be 0.** Then we must decide a, b, and c. { **a** (multiplied by x^2) is **3** and the **b** (multiplied by x) is** -1** and **c** (the “lone number” is** -2**}

Do you see that b is -1 so that means -b is +1. Now **look under the square root **and recall Order of Operation rules. We will get 1 – 12(-2) or 1+24.

Now test your solutions (answers for x). Will the 1 make the quadratic expression above =0? Will the -2/3 also make the above expression =0? **They should!**
