Question

(5x+2)(-x-4)=0 ......

Answer 1

Ответ:

Пошаговое объяснение:

если произведение двух скобок равно нулю то одна из скобок должна равняться нуло

5x+2=0                              или  -x-4=0

5x=-2                                         -x=4

x=-2/5=-0,4                                 x=4

Ответ: x1=-0,4 x2=4

Answer 2

х= -0.4

х= -4

вот таков у нас ответ

Answer 3

To solve the given equation $(5x + 2)(-x - 4) = 0$, we can use the zero product property. The zero product property states that if the product of two factors is equal to zero, then at least one of the factors must be equal to zero.

So, in this case, we have:

$(5x + 2)(-x - 4) = 0$

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

1. $5x + 2 = 0$ Subtract 2 from both sides: $5x = -2$ Divide both sides by 5: $x = -\frac{2}{5}$

2. $-x - 4 = 0$ Add 4 to both sides: $-x = 4$ Multiply both sides by -1 to solve for $x$: $x = -4$

So, the solutions for the equation $(5x + 2)(-x - 4) = 0$ are $x = -\frac{2}{5}$ and $x = -4$.
