A) $x = \sqrt { 2 }$
B) $x = 0 \text { or } x = \sqrt { 2 }$
C) x = 2
D) x = 0 or x = 2

Quizplus · Accepted Answer

We can factor out x from the equation: x(x-2)=0. Then we apply the property ab=0 if and only if a=0 or b=0, we have either x=0 or x-2=0. Thus, x=0 or x=2. Therefore, the best choice is D.
