我们经常看到,一些方程、不等式的求解过程计算量较大,而检验过程计算量仍较大.如例1 解不等式 3-x~(1/2)-x+1~(1/2)>1/2 略解:两次两边平方、
We often see that some equations and inequalities have large computational costs in the solution process, while the verification process still has large calculations. Example 1 Solution Inequality 3-x~(1/2)-x+1~(1/2) >1/2 Slightly solution: twice squared on both sides,
