Question

(8-0,3x)(2x+9)=0 ???​

Answer 1

Ответ:

-4.5, 26 2/3

Пошаговое объяснение:

Кожну дужка = 0

8-0.3х=0

0.3х=8

х= 26 2/3

2х+9=0

2х=-9

х=-4.5

Answer 2

To solve the equation (8 - 3x)(2x + 9) = 0, you 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. In this case, you have two factors:

Factor 1: 8 - 3x Factor 2: 2x + 9

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

1. 8 - 3x = 0 Add 3x to both sides: 8 = 3x Divide by 3: x = 8/3

2. 2x + 9 = 0 Subtract 9 from both sides: 2x = -9 Divide by 2: x = -9/2

So, the solutions to the equation are: x = 8/3 and x = -9/2.
