Answer 2

Step-by-step explanation:

Given Quadratic Equation → √6x² - 4x - 2√6 = 0

When questions that cannot be easily factorized by splitting the middle term are given, then go for factorizing it by using Quadratic Formula.

$\bf{x = \dfrac{-b \pm \sqrt{b^{2}-4ac} }{2a}}$

Compare this with the general form of Quadratic Equation i.e. ax² + bx + c = 0.

We observe that:

• a = √6
• b = -4
• c = -2√6

Substitute these values in the formula.

$\leadsto \: \sf{x = \dfrac{4\pm \sqrt{(-4)^{2}-4(\sqrt{6})(-2\sqrt{6})}}{2\sqrt{6}}}$

$\implies \sf{x = \dfrac{4 \pm \sqrt{16+48} }{2\sqrt{6}}}$

$\implies \sf{x = \dfrac{4 \pm \sqrt{64} }{2 \sqrt{6}}}$

$\implies \sf{x = \dfrac{4 \pm 8 }{2 \sqrt{6}}}$

Taking positive sign,

$\sf{x = \dfrac{12}{2\sqrt{6}}=\dfrac{6}{\sqrt{6}}=\sqrt{6}}$

Taking negative sign,

$\sf{x = \dfrac{-4}{2\sqrt{6}}=-\dfrac{\sqrt{6}}{3}=-\sqrt{\dfrac{2}{3}}}$

$\therefore \: \boxed{\boldsymbol{x=\sqrt{6} \: \: or \: \: -\sqrt{\dfrac{2}{3}}}}$
