Question

If s is set of all real x such that (2x-1)/(2x^3+3x^2+x) is positive then s contains

Answer 1

Answer:

The set 's' is given by:

$s=\{x\ belongs\ to\ real\ numbers|x\geq \dfrac{1}{2}\}$

Step-by-step explanation:

s denote the set of all the real numbers such that:

$\dfrac{2x-1}{2x^3+3x^2+x}$ is positive.

i.e.

$\dfrac{2x-1}{2x^3+3x^2+x}\geq 0$

i.e.

$2x-1\geq 0$

i.e.

$2x\geq 1\\\\x\geq \dfrac{1}{2}$

Hence, the set s is the set of all the real numbers ''x'' such that: $x\geq \dfrac{1}{2}$
