The interval of solution of equation 2x + X-2 = 0 is () A. （-1，0）B. （0，1）C. （1，2）D. （2，3）

Let f (x) = 2x + X-2, because f (0) = - 2 ＜ 0, f (1) = 1 ＞ 0, f (0) f (1) ＜ 0, according to the judgment theorem of function zero point, we can get that the interval of the zero point of F (x) is (0, 1), so the interval of the solution of equation 2x + X-2 = 0 is (0, 1), so we choose B
