Question

-2 корнем уравнения а(а+1)=0

Answer 1

Ответ:

Не является

Пошаговое объяснение:

Если подставить -2 вместо a, то

-2*(-2+1)=-2*(-1)=2

2≠0

Answer 2

To find the roots of the equation $a(a+1) = 0$, we need to set the equation equal to zero and solve for the variable $a$. When the product of two numbers is zero, it means that at least one of the numbers must be zero.

So, we have:

$a(a + 1) = 0$

Now, we set each factor equal to zero:

1. $a = 0$
2. $a + 1 = 0$

Solving for $a$ in each case:

1. $a = 0$
2. $a = -1$

Therefore, the roots of the equation are $a = 0$ and $a = -1$.
