(2x - 3)² - (2x - 3)²
4x² - 9 - 4 x² + 9
All of these gets cancelled.
Thus ,
(2x - 3)² - (2x - 3)² = 0
4x² - 9 - 4 x² + 9
All of these gets cancelled.
Thus ,
(2x - 3)² - (2x - 3)² = 0

(2x - 3)^2 - (2x - 3)^2
= 4x^2 - 2.2x.3 + 9 - ( 4x^2 - 2.2x.3 + 9) [We know that (a-b)^2 = a^2 - 2ab + b^2]
= 4x^2 - 12x + 9 - 4x^2 + 12x - 9 [ removing the braket]
= 0
Hope it helps.
