The original formula X is a variable, and after transformation, you can solve it as a function of m as a variable.
Inequality 2x-1>; m(x & amp； Sup2- 1) can be changed to (x &；; sup2- 1)m-(2x- 1)& lt； 0?
Let f (m) = (x&; sup2- 1)m-(2x- 1)
Make inequality (x&; sup2- 1)m-(2x- 1)& lt； For the m∈ constant of 0, then:
f(-2)& lt； 0 and f (2) < 0? ((adopting the thinking method of attribute combination))
That is, (x&; sup2- 1)*(-2)-(2x- 1)& lt； 0 and (x&; sup2- 1)* 2-(2x- 1)& lt； 0
Solution:? (- 1+√7)/2 & lt； x & lt( 1+√3)/2
The formula in the penultimate line above can be listed with reference to the figure below.
