Question

Solve x^2-4x=0 solving quadratic equations

Answer 1

`x= 0\\x =4`

Explanation:

We have the expression:

`x ^ 2-4x = 0`

To solve this equation we must factor:

1.- Take common factor x.

`x(x-4) = 0`

2.- Evaluate the expressions to know when they are equal to 0.

`x = 0` or
`x-4 = 0`

`x = 0` or
`x = 4`

3.- The solutions are:

`x = 0\\x = 4`
