Answer 1

(2x - 1/2x)²
= 2²x² - 2 x 2x x 1/2x + (1/2x)²
= 4x² - 2 x 2x x 1/2x + 1/4x²
= 4x² - 4x/2x + 1/4x²
= 4x² - 2 + 1/4x²

16x² - 64y²
= 16(x² - 4y²)
= 16(x² - (2y)²)
= 16(x+2y)(x-2y)

6x² + x - 15
= 6x² + 10x - 9x - 15
= 2x(3x+5) - 3x(3x+5)
= (3x+5)(2x-3)

Maaf kalau salah
Semoga membantu ya ^_^
