Question

Решите: x+x^2 = 0 и 0/0=___

Answer 1

Ответ: $x_1=-1$

$x_2=0$

0/0=на ноль делить нельзя, ну а тк то 0/0=0

Answer 2

1) = х*(1+х)=0

х=0
1+х=0

Х1=0 х2=-1

2) 0/0 - на ноль делить нельзя

Answer 3

To solve the equation x + x^2 = 0, we can factor it:

x + x^2 = 0 x(1 + x) = 0

Now, the equation is satisfied when either x = 0 or (1 + x) = 0.

1. If x = 0: Substituting x = 0 into the equation, we get: 0 + 0^2 = 0 0 = 0

2. If (1 + x) = 0: Subtracting 1 from both sides, we get: 1 + x - 1 = 0 - 1 x = -1

So, the solutions to the equation are x = 0 and x = -1.

Regarding 0/0, it is undefined in mathematics. Division by zero is not allowed because it leads to contradictions and indeterminate results. In other words, there is no number that, when multiplied by 0, will give a specific value (i.e., 0/0 does not have a unique solution). Therefore, 0/0 is undefined.
