Question

Valorile ale lui x pebtry cae avem 2x√3 - 4√3 < 2x-4 sunt egale cu

Answer 1

$2x \sqrt{3} - 4 \sqrt{3} < 2x - 4$

$2x \sqrt{3} - 2x < - 4 + 4 \sqrt{3}$

$2x( \sqrt{3} - 1) < 4( - 1 + \sqrt{3} )$

$2x( \sqrt{3} - 1) < 4( \sqrt{3} - 1) \: | \div ( \sqrt{3} - 1)$

$2x < 4 \: | \div 2$

$x < 2$

$x \: \in \: ( - \infty ,2)$
