问题 If (x-1)2=144, which of the following could be the value of 2x?

选项 A、-26
B、-22
C、-11
D、12
E、13

答案 B

解析 Since there are only two possible values of 2x, it’s easiest to start with them and find one that is also in the answer choices. Since (x-1)2 could equal either 12 or -12, x could equal 13 or -11, which means that 2x could equal either 26 or -22. Of the answers, only B will work.
