Question

$\log _{2}\left(\frac{10 x-4}{4-x^{2}}\right) \geq 1$

$\Rightarrow \frac{10 x-4}{4-x^{2}}-2 \geq 0 $

$\Rightarrow \frac{x^{2}+5 x-6}{4-x^{2}} \g

Vedclass · Answer

$\log _{2}\left(\frac{10 x-4}{4-x^{2}}\right) \geq 1$

$\Rightarrow \frac{10 x-4}{4-x^{2}}-2 \geq 0 $

$\Rightarrow \frac{x^{2}+5 x-6}{4-x^{2}} \geq 0$

$\Rightarrow \frac{(x+6)(x-1)}{(x-2)(x+2)} \leq 0$
