Question

Решите пж (2х-5)*(3х+0,3)=0

Answer 1

(2x-5)(3x+0,3)=0

2x-5=0 или 3x+0,3=0

2x=0+5 или 3x=0-0,3

2x=5 или 3x=-0,3

x=5:2 или x=-0,3:3

x=2,5 или x=-0,1

Ответ:x=2,5;x=-0,1

Answer 2

To solve the equation (2x-5)*(3x+0.3) = 0, we need to find the values of x that make the entire expression equal to zero. To do this, we 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, we set each factor to zero and solve for x:

1. 2x - 5 = 0: Add 5 to both sides: 2x = 5 Divide by 2: x = 5/2 x = 2.5

2. 3x + 0.3 = 0: Subtract 0.3 from both sides: 3x = -0.3 Divide by 3: x = -0.3/3 x = -0.1

The solutions to the equation are x = 2.5 and x = -0.1.
