Question

hallar el valor de x

​

Answer 1

X^2 = 22 + 10 = 32

X^2 = 32 × 2 = 64

X^2 = 64

X = 8

Answer 2

Respuesta:

$x_{1}=8\:\:\:\: \: \: \: \: \: \:\:\:x_{2}=-8$

Explicación paso a paso:

$\frac{ {x}^{2} }{2} - 10 = 22$

$\frac{ {x}^{2} }{2} = 22 + 10$

$\frac{ {x}^{2} }{2} = 32$

${x}^{2} = 32 \times 2$

${x}^{2} = 64$

$x = \pm \sqrt{64}$

$x = \pm8$

$x_{1}=8\:\:\:\: \: \: \: \: \:\:\:x_{2}=-8$
