because,
squaring both sides,
x = 3/32
Option C is the right answer
The absolute value of x: |x|.
|x| = x if x ≥ 0 <em>examples: |5| = 5; |0| = 0; |8.34| = 8.34; |1/2| = 1/2</em>
|x| = -x if x < 0 <em>examples: |-5| = -(-5) = 5; |-8| = -(-8) = 8; |-1.2| = 1.2;</em>
<em> |-3/7| = 3/7</em>
<em>Therefore</em>
