Question

X²+ 4x=0,​

Answer 1

Ответ:

Объяснение:

1) x(x+4)=0

x1= 0

x2= -4

2) D= 49-24= 25

x1= (-7+5)/ 6= -1/3

x2= (-7-5)/6= -2

Answer 2

To solve the quadratic equation $x^2 + 4x = 0$, we need to find the values of $x$ that satisfy the equation. To do this, we can use factoring. The equation can be rewritten as follows:

$x^2 + 4x = x(x + 4) = 0$

Now, we have a product of two factors that equals zero. According to the zero-product property, one or both of the factors must be equal to zero to make the whole equation true.

So, we set each factor equal to zero and solve for $x$:

1. $x = 0$
2. $x + 4 = 0$

Solving equation 2 for $x$:

$x + 4 = 0$
$x = -4$

The solutions to the quadratic equation are $x = 0$ and $x = -4$.
