Question

(2x+0.2)(x-0.5)=0 и x-(-5)=5

Answer 1

2x+0,2=0
2x=-0,2
x=0,2:2
x=0,1 

x-0,5=0
x=0,5
ответ (0,1 ; 0,5)

x-(-5)=5
x+5=5
x=0
ответ 0

Answer 2

Let's solve the given equations step by step.

Equation 1: (2x + 0.2)(x - 0.5) = 0

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

2x + 0.2 = 0 2x = -0.2 x = -0.2/2 x = -0.1

x - 0.5 = 0 x = 0.5

Therefore, the solutions to equation 1 are x = -0.1 and x = 0.5.

Equation 2: x - (-5) = 5

Simplifying the equation:

x + 5 = 5

Subtracting 5 from both sides:

x = 0

The solution to equation 2 is x = 0.

In summary, the solutions to the given equations are: Equation 1: x = -0.1 and x = 0.5 Equation 2: x = 0
