Step-by-step explanation:
Answer:
![1- ( { 2 x - 1)}^{2} = 4x (1 - x )](https://tex.z-dn.net/?f=1-%20%28%20%7B%202%20x%20-%201%29%7D%5E%7B2%7D%20%3D%20%204x%20%281%20%20-%20x%20%29)
Step-by-step explanation:
We want to to rewrite
![1 - ( { 2 x - 1)}^{2}](https://tex.z-dn.net/?f=1%20-%20%28%20%7B%202%20x%20-%201%29%7D%5E%7B2%7D%20)
Use difference of two squares to get:
![{a}^{2} - {b}^{2} = (a + b)(a - b)](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20-%20%20%7Bb%7D%5E%7B2%7D%20%20%3D%20%28a%20%2B%20b%29%28a%20-%20b%29)
This implies that:
![{1}^{2} - ( { 2 x - 1)}^{2} = (1 +( 2x - 1))(1 - (2x - 1))](https://tex.z-dn.net/?f=%7B1%7D%5E%7B2%7D%20-%20%28%20%7B%202%20x%20-%201%29%7D%5E%7B2%7D%20%20%3D%20%281%20%2B%28%202x%20-%201%29%29%281%20%20-%20%282x%20%20-%201%29%29)
![{1}^{2} - ( { 2 x - 1)}^{2} = (1 + 2x - 1)(1 - 2x + 1)](https://tex.z-dn.net/?f=%7B1%7D%5E%7B2%7D%20-%20%28%20%7B%202%20x%20-%201%29%7D%5E%7B2%7D%20%20%3D%20%281%20%2B%202x%20-%201%29%281%20%20-%202x%20%20%20%2B%201%29)
This finally simplifies to:
![{1}^{2} - ( { 2 x - 1)}^{2} = 2x (2 - 2x )](https://tex.z-dn.net/?f=%7B1%7D%5E%7B2%7D%20-%20%28%20%7B%202%20x%20-%201%29%7D%5E%7B2%7D%20%20%3D%20%202x%20%282%20%20-%202x%20%29)
Therefore the required product is
![2x (2 - 2x ) = 4x(1 - x)](https://tex.z-dn.net/?f=%202x%20%282%20%20-%202x%20%29%20%3D%204x%281%20-%20x%29)
