Answer:
(3x - 1/6)(x + 5/6)
Step-by-step explanation:
We can use the identity of a² - b² = (a + b)(a - b).
=> (2x + 1/3)² - (x - 1/2)² = a² - b²
Comparing, a = (2x + 1/3) and b = (x - 1/2).
=> (a + b)(a - b)
=> (2x + 1/3 + x - 1/2)(2x + 1/3 - {x - 1/2})
=> (3x - 1/6)(2x + 1/3 - x + 1/2) [Minus and plus combine to become minus]
=> (3x - 1/6)(x + 5/6) is the factorization of (2x + 1/3)² - (x - 1/2)².
If you want to open it, it will become:
=> (3x - 1/6)(x + 5/6)
=> 3x(x) + 3x(5/6) - 1/6(x) - 1/6(5/6)
=> 3x² + 5x/2 - x/6 - 5/36
=> 3x² + (15x - x/6) - 5/36
=> 3x² + 14x/6 - 5/36
=> 3x² + 7x/3 - 5/36 is the expansion of (3x - 1/6)(x + 5/6).
