Question

Vă rog !!! Dau coroana !!!​

Answer 1

Răspuns:

$(x - \sqrt{2} ) {}^{2} = \frac{8}{9 } \\ x - \sqrt{2} = \sqrt{ \frac{8}{9} } \\ x - 2 = - \frac{2 \sqrt{2} }{3} \\ x1 = \frac{ \sqrt{2} }{3} \\ x2 = \frac{5 \sqrt{2} }{3}$

Deci are două soluti:

$x1 = \frac{ \sqrt{2} }{3}$

$x2 = \frac{5 \sqrt{2} }{3}$
