Question

5×(2х-8)×(4-х)=0 решить уравнение ​

Answer 1

Чтобы произведение равнялось 0 достаточно, чтобы один из множителей был равен 0.

5 · (2х - 8) · (4 - х) = 0

5 ≠ 0          2х - 8 = 0                    4 - х = 0

                  2х = 8                         - х = - 4

                  х = 8 : 2                       х = 4

                  х = 4

Answer 2

Ответ:

2x-8=0или4-х=0

2х-8=0

2х=8

Х=4

4-х=0

-Х=-4

Х=4

Answer 3

To solve the equation 5×(2х-8)×(4-х) = 0, we can set each factor equal to zero and solve for x.

First factor: 5 = 0 This is not true, so we can discard this factor.

Second factor: (2x - 8) = 0 Add 8 to both sides: 2x - 8 + 8 = 0 + 8 2x = 8 Divide both sides by 2: 2x/2 = 8/2 x = 4

Third factor: (4 - x) = 0 Subtract 4 from both sides: 4 - x - 4 = 0 - 4 -x = -4 Multiply both sides by -1 (to isolate x): (-1)(-x) = (-1)(-4) x = 4

So the solutions to the equation 5×(2х-8)×(4-х) = 0 are x = 4.
