Question

|x-√2|=√2
Va rog ajutatima

Answer 1

|x- √2| =√2
x-√2=√2      sau     x-√2= -√2
x=√2+√2                x= -√2+√2=0
x=2√2            sau  x= 0

Answer 2

$|x- \sqrt{2} |= \sqrt{2} \\ x- \sqrt{2} = \sqrt{2} \\ x= \sqrt{2} + \sqrt{2} \\ x=2 \sqrt{2} \\ x- \sqrt{2}=- \sqrt{2} \\ x=- \sqrt{2} + \sqrt{2} \\ x=0$
