Question

(2x+3)×(2x+5)=0help me ​

Answer 1

(2x+3)×(2x+5)=0

2х+3=0;                      2х+5=0

2х = -3                         2х = -5

х = -3/2                         х= -5/2

х= -1,5                          х = -2,5

Ответ: корни уравнения х1 = - 1,5; х2 = -2,5.

Answer 2

Ответ:

2х+3=0

х1=-1,5

2х+5=0

х2=-2,5

Answer 3

To solve the equation (2x + 3) × (2x + 5) = 0, you need to find the values of x that make the equation true. To do that, you can use the zero-product property, which states that if the product of two or more factors is equal to zero, then at least one of the factors must be equal to zero.

So, in this case, you have:

(2x + 3) × (2x + 5) = 0

To find the values of x, set each factor to zero and solve for x:

1. Set (2x + 3) = 0 and solve for x: 2x + 3 = 0 Subtract 3 from both sides: 2x = -3 Divide by 2: x = -3/2

2. Set (2x + 5) = 0 and solve for x: 2x + 5 = 0 Subtract 5 from both sides: 2x = -5 Divide by 2: x = -5/2

So, the solutions to the equation are x = -3/2 and x = -5/2.
