Question

(6х – 9) (4х + 0,4) = 0. Найдите корень уравнения.

Answer 1

(6х – 9) (4х + 0,4) = 0
6x - 9 = 0 
6x = 9 
x = 1,5
4x + 0,4 = 0
4x = - 0,4 
x = - 0,1 
Ответ ( - 0,1 ) ; 1,5 

Answer 2

6х-9=0;
6х=9
х=9/6
х=1,5

4х+0,4=0
4х=-0,4
х=-0,4/4
х= -0,1
Ответ:х1=1,5;х2= -0,1

Answer 3

To find the root of the equation, we need to solve it for x. The equation is:

(6x - 9)(4x + 0.4) = 0

To find the roots, we set each factor equal to zero and solve for x:

1. 6x - 9 = 0 Add 9 to both sides: 6x = 9 Divide by 6: x = 9/6 x = 1.5

2. 4x + 0.4 = 0 Subtract 0.4 from both sides: 4x = -0.4 Divide by 4: x = -0.4/4 x = -0.1

So, the two roots of the equation are x = 1.5 and x = -0.1.
