**Question: 564**

**21.** If *x*^{2} - |5*x*| = -6, then what is one possible value of *x* ?

A. -5

B. -2

C. 0

D. 5

E. 6

**Correct Answer:** B

**Explanation:**

**B** Here is a chance to use Plugging In The Answers. Start with the middle value in C and see which makes the equation true: It is not possible for *x* to be 0, because 0^{2} – |0| ≠ –6. The larger values don't equal –6 either: D gives 0 while E gives positive 6. B is correct: (–2)^{2} – |?10| = 4 – 10 = –6.
