Question

( x al cuadrado+ 2 ) /3-2=15

Answer 1

Respuesta:

x = 7

Explicación paso a paso:

($x^{2}$ + 2)/3 - 2 = 15

$(x^{2}$ + 2)/3 = 15 + 2

($x^{2}$ + 2)/3 = 17

$x^{2}$ + 2 = 17(3)

$x^{2}$ + 2 = 51

$x^{2}$ = 51 - 2

$x^{2}$ = 49

x = $\sqrt{49}$

x = 7

Answer 2

Explicación paso a paso:

$\frac{x^{2}+2 }{3} -2 = 15$

$\frac{x^{2}+3 }{3} = 15 +2$

$x^{2} +2 = 17 . 3$

$x^{2} = 51 - 2$

$|x| = \sqrt{49}$

x1 = 7

x2= -7
