If (x + 2)^2 = 144, which of the following could be the value of 2x?	Choose the correct choice from the following:	A) –26	B) –22	C) –11	D) 12	E) 14
You can also get to the answer by backsolving using answer choices   Starting with choice C = -14   (x + 2)^2 = 144   (-14 + 2)^2 = 144 =====&gt; (-12)^2 = 144 Bingo, Clearly, among the answer choices only -14 will result in 144 in the equation so x must be -14,   Then 2x = 2 * -18 = -22   Answer: 14
