Solve the equation :
(2x - 1)3 + 2x(2x - 3).(3 - 2x) – (3x - 1)2 = 3x2 - 2 Choose one:
A) 0
B) 1
C) 2
D) 3
E) 4
Solution:   We open the brackets by using the formulas for multiplication:   8x3 - 3(2x)2.1 + 3.2x(1)2 – 13 - 2x(2x - 3)2 – (9x2 - 6x + 1) = 3x2 - 2 &lt;=&gt;   8x3 - 12x2 + 6x - 1 - 2x(4x2 - 12x + 9) - 9x2 + 6x - 1 = 3x2 - 2 &lt;=&gt;   8x3 - 21x2 + 12x - 8x3 + 24x2 - 9x = 3x2 &lt;=&gt;   3x2 + 3x = 3x2 &lt;=&gt;   3x = 0 &lt;=&gt; x = 0   0nswer 0
