**Question: 24**

**2.** If the square of x is 12 less than the product of x and 5, which of the following expressions could be used to solve for x?

A. x2 = 5x - 12

B. x2 = 12 - 5x

C. 2x = 12 - 5x

D. 2x = 5x - 12

E. x2 = (x + 5) - 12

**Correct Answer:** A

**Explanation:**

A. Don't fall for the old "less than" trick. "Twelve less than something" is the thing minus 12 — not the other way around. So you want an expression that says "x squared is 5 times x minus 12," and (A) is the winner.
