Question

${x}^{2} - 12 \times + 10 = 0$
me ajudeeem, PFVRRRR​

Answer 1

$x^{2} - 12x + 10 = 0$

$x^{2} - 12x + 10 - 10 = - 10$

$x^{2} - 12x = - 10$

$x^{2} - 12x + (-6)^{2} = - 10 + (-6)^{2}$

$x^{2} - 12x + 36 = -10 + 36$

$x^{2} - 12x + 36 = 26$

$(x - 6)^{2} = 26$

$\sqrt{(x - 6)^{2}$ = $\sqrt{26}$

$x - 6 = \sqrt{26}$

$x - 6 = -\sqrt{26}$

_

$x = \sqrt{26} + 6 = 11.099019514$

$x + 6 - \sqrt{26}$ $= 0.900980486$

Espero ter ajudado :)
