Question

solve work by using square root method

Answer 1

$~~~~(x-2)^2 = 16\\\\\implies x-2 = \pm\sqrt{16}\\\\\implies x-2 = \pm4\\\\\implies x= \pm4 +2\\\\\implies x=-4+2~~ \text{or}~~ 4+2\\\\\implies x = -2~~ \text{or}~~ 6$

Answer 2

Answer:

$x = - 2$

$x = 6$

Step-by-step explanation:

$(x - 2)^{2} = 16$

$x - 2 = ± \: 4$

$x - 2 = - 4$

$x - 2 = 4$

$x = - 2$

$x = 6$
