Question

(x+4)(x-4)-(x+12)^2

Answer 1

Ответ:

(Х-4)(х+4)=х²-16(разница квадратов)

(х+12)²=х²+24х+144

Х²-16-х²-24х-144=-144-40х

Answer 2

Let's simplify the expression step by step:

1. Expand the first term: (x + 4)(x - 4) = x^2 - 4x + 4x - 16 = x^2 - 16

2. Expand the second term: (x + 12)^2 = x^2 + 2 * x * 12 + 12^2 = x^2 + 24x + 144

3. Subtract the expanded second term from the expanded first term: (x^2 - 16) - (x^2 + 24x + 144)

   Simplify each term:

   x^2 - 16 - x^2 - 24x - 144 = -40x - 160

So, the simplified expression is -40x - 160.
