Answer 2

$\huge\color{green}{\underline{answer\::}}$

1. 24a² - 2a² - 5

2. x²/4 - 27x/4 - 14

1. (12a²+ 5) (2a² - 1)

12a² (2a² - 1) + 5 (2a² - 1)

24a⁴ - 12a² + 10a² - 5

24a² - 2a² - 5

2. ( x + 2) (x/4 - 7)

x (x/4 - 7) + 2 (x/4 - 7)

x²/4 - 7x + 2x/4 - 14

x²/4 - 7x + x/4 - 14

x²/4 (- 28 x + x)/4 - 14

x²/4 - 27x/4 - 14
