If (x – 1)^2 = 144, which of the following could be the value of 2x? Choose the correct choice from the following answers:
A) –26
B) –22
C) –11
D) 12
E) 13
If (x-1)^2 = 144   then (x-1) = Sq rt 144   = 12 ( can have both positive and negative values)   If positive   then (x-1) = 12   =&gt; x = 13 =&gt; 2x = 26   If negative   then (x-1) = -12   =&gt; x = -12+1 = -11 =&gt; 2x = -22   Out of options given, we can see B has -22 value .   Hence option –22
