Question

(5x+2)(-x-4)=0 help me​

Answer 1

(5х+2)(-х-4)=0
5х+2=0
5x=-2
X=-2/5
-x-4=0
-x=4
X=-4
Ответ:-2/5;х=-4

Answer 2

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

So we have two factors:

1. $5x + 2$
2. $-x - 4$

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

1. $5x + 2 = 0$ $5x = -2$ $x = -\frac{2}{5}$

2. $-x - 4 = 0$ $-x = 4$ $x = -4$

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