|(2x + 1)2 - 4x2 - 2| - 3|4x – 1| = - 6 Choices.
A) -1/2
B) 1/2
C) -3/4
D) 3
E) None
Solution:   |(2x + 1)2 - 4x2 - 2| – 3|4x -1| = - 6 &lt;=&gt;   |4x2 + 4x + 1 - 4x2 - 2 | - 3|4x - 1| = - 6 &lt;=&gt;   |4x – 1| - 3|4x – 1| = - 6 &lt;=&gt; -2|4x – 1| = - 6 &lt;=&gt;   |4x – 1| = 3 &lt;=&gt; 4x - 1 = 3 or 4x - 1 4  - 1=
