If (x + 1)^2 = 144, which of the following could be the value of 2x?	Choose the correct choice from the following:
A) –26	B) –13	C) –10	D) 12	E) -21
You can also get to the answer by backsolving using answer choices   Starting with choice B = -13   (x + 1)^2 = 144   (-13 + 1)^2 = 144 =====&gt; (-12)^2 = 144 Bingo, Clearly, among the answer choices only -13 will result in 144 in the equation so x must be -11,   Then 2x = 2 * -13 = -26   –26nswer: –26
