Question

Solve for x. 2x2 − 4x = 0

Answer 1

x = 2

Explanation:

From my understanding, this question is

2x² - 4x = 0

Step 1: Take x as common

2x² - 4x = 0

x(2x - 4) = 0

2x - 4 = 0/x

2x - 4 = 0

Step 2: Solve to find x

2x - 4 = 0

2x = 4

x = 4/2

x = 2

Therefore, the value of x after solving is x = 2

Answer 2

`x = 0` and
`x = 2`

Explanation:

We have the following quadratic equation

`2x^2 - 4x = 0`

Take 2x as a common factor

`2x(x - 2) = 0`

Note that equality is met when either factor equals zero.

That is to say:

`2x = 0` →
`x = 0`

`(x-2) = 0` →
`x = 2`

Finally the solutions of the equation are:

`x = 0` and
`x = 2`
