Решите уравнение (3х-8)^2-(4x-6)^2+(5x-2)(x+2)=24

Вычислим х.

(3 * х - 8) - (4 * x - 6) + (5 * x - 2) * (x + 2) = 24; 

(3 * x) - 2 * (3 * x) * 8 + 8 - ((4 * x) - 2 * (4 * x) * 6 + 6) + (5 * x) + 5 * 2 * x - 2 * x - 2 * 2 = 24; 

9 * x - 6 * 8 * x + 64 - (16 * x - 8 * x * 6 + 36) + 25 * x + 10 * x - 2 * x - 4 = 24; 

9 * x - 48 * x + 64 - (16 * x - 48 * x + 36) + 25 * x + 8 * x - 4 = 24; 

9 * x - 48 * x + 64 - 16 * x + 48 * x - 36 + 25 * x + 8 * x - 4 = 24; 

9 * x + 64 - 16 * x  - 36 + 25 * x + 8 * x - 4 = 24; 

x * (9 - 16 + 25) + 8 * x + (64 - 36 - 4) = 24; 

8 * x + 60 - 36 = 24; 

8 * x = 24 + 36 - 60; 

8 * x = 0; 

x = 0.
