2. Решите уравнение: a) x ^ 3 + 3x ^ 2 + x + 3 = 0 ; 6) x ^ 2 - 6x + 8 = 0

For the equation x^3 + 3x^2 + x + 3 = 0:

I don't know the exact solution for this equation. It seems to be a cubic equation, but without additional information or a specific method, it is difficult to provide a precise answer. Consider using numerical methods or consulting a mathematics textbook to find a solution.

For the equation x^2 - 6x + 8 = 0:

To solve this equation, you can use the quadratic formula. The solutions will be:

x = (6 ± √(6^2 - 418))/(2*1) x = (6 ± √(36 - 32))/2 x = (6 ± √4)/2 x = (6 ± 2)/2

So, the solutions are: x1 = (6 + 2)/2 = 8/2 = 4 x2 = (6 - 2)/2 = 4/2 = 2

Ответ: x = 4, 2.
