Question

(-5x - 3) (2x - 5) = 0

Answer 1

Ответ:

-0.6 ; 2.5

Пошаговое объяснение:

(-5x - 3) (2x - 5) = 0

-5x-3=0

-5x=3

x= -3/5 = -0.6

2x-5=0

2x=5

x=2.5

Answer 2

To solve the equation $(-5x - 3)(2x - 5) = 0$, you need to find the values of $x$ that make the equation true. This equation is a product of two factors equaling zero. According to the zero product property, if the product of two factors is zero, at least one of the factors must be zero.

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

1. $-5x - 3 = 0$ Add 3 to both sides: $-5x = 3$ Divide by -5: $x = -\frac{3}{5}$

2. $2x - 5 = 0$ Add 5 to both sides: $2x = 5$ Divide by 2: $x = \frac{5}{2}$

So, the solutions for $x$ are $x = -\frac{3}{5}$ and $x = \frac{5}{2}$ because these are the values of $x$ that make either of the factors equal to zero.
