Question

(6x-9)•(4x+0,4)=O решите

Answer 1

Произведение тогда равно нулю когда один из множителей равен 0
6х-9=0 4х+0,4=0
6х=9 |:3 4х=-0,4 |:4
2х=3. х=-0,1
х=1,5

Answer 2

To solve the equation (6x - 9) * (4x + 0.4) = 0, we need to find the values of x that make the equation true.

To do this, we can set each factor equal to zero and solve for x:

1. Set (6x - 9) equal to zero: 6x - 9 = 0 Add 9 to both sides: 6x = 9 Divide both sides by 6: x = 9/6 x = 3/2

2. Set (4x + 0.4) equal to zero: 4x + 0.4 = 0 Subtract 0.4 from both sides: 4x = -0.4 Divide both sides by 4: x = -0.4/4 x = -0.1

So, the solutions to the equation are x = 3/2 and x = -0.1.
