Bất phương trình \(2x + \dfrac{3}{{2x - 4}} < 5 + \dfrac{3}{{2x - 4}}\) tương đương với:

\(x = 1\)          

\(x =  - 3\)       

\(x = 0\)

\(x =  - 1\)

\(S = \left\{ { - 2; - 1;0;1;2;3;4} \right\}\)

\(\left\{ 0 \right\} \in S\)

\(S = \left[ { - 2;4} \right]\)

\(S = \left\{ { - 2;4} \right\}\)

\(x \ge 0\)

\(x \le  - 1\)

\(x \ge  - 1\)

\( - 1 \le x \le 0\)

\(D = \left[ {4;5} \right].\)

\(D = \left( { - 5;4} \right].\)

\(D = \left[ {4;5} \right).\)

\(D = \emptyset .\)

\(D = \left[ {1; + \infty } \right).\)

\(D = \left( {1; + \infty } \right).\)

\(D = \left[ {1; + \infty } \right)\backslash \left\{ 2 \right\}.\)

\(D = \left( {1; + \infty } \right)\backslash \left\{ { - 2} \right\}.\)

$m = 3.$

$m < 3.$

$m > 3.$

\(m \le 3\)
