Explicación paso a paso:

(x-2)² =25

x-2=±5

x-2= -5

x-2=5

x= -3

x=7

x = -3,x2=7

Answer 2

${(x - 2)}^{2} = 25$

${( x - 2)}^{2} = {5}^{2}$

${(x - 2)}^{2} - {5}^{2}$=0

$(x - 2 + 5)(x - 2 - 5) = 0$

$(x + 3)(x - 7) = 0$

$x + 3 = 0$

$x = - 3$

$x - 7 = 0$

$x = 7$

los valores de X son -3 y 7
