Answer:

4a²-1 = (2a - 1) (2a + 1)

Step-by-step explanation:

Formula : a^2 - b^2 = (a - b) (a +b)

4a²-1

Write this in a² - b² format

= (2a)² - (1)²

= (2a - 1) (2a + 1)

So,  4a²-1 = (2a - 1) (2a + 1)

 = 4 {a}^{2}  - 1

 {a}^{2}  -  {b}^{2}  = (a + b)(a - b)

 = (2a - 1)(2a + 1)

 = 2 {a}^{2}  -  {1}^{2}

4 {a}^{2}  - 1 = (2a + 1)(2a - 1)
