(8x +4) (0,2x-3)=0 .....................​

Answer 1

Ответ:

Пошаговое объяснение:

(8x +4) (0,2x-3)=0

8x + 4 = 0  или  0,2x - 3 = 0

8x = -4                 0,2x = 3

x = -4:8                 x = 3 : 0,2

x = -0,5                 x = 15

ответ: x₁ = -0,5 ;       x₂ = 15

Answer 2

To solve the equation (8x + 4)(0.2x - 3) = 0, you can use the zero-product property, which 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, you can set each factor equal to zero and solve for x separately:

1. 8x + 4 = 0
2. 0.2x - 3 = 0

Let's solve these equations one by one:

1. 8x + 4 = 0 Subtract 4 from both sides: 8x = -4 Now, divide by 8: x = -4/8 x = -1/2

2. 0.2x - 3 = 0 Add 3 to both sides: 0.2x = 3 Now, divide by 0.2: x = 3/0.2 x = 15

So, the solutions to the equation (8x + 4)(0.2x - 3) = 0 are x = -1/2 and x = 15.
