Answer:

[tex]x= 0\\x =4[/tex]

Step-by-step explanation:

We have the expression:

[tex]x ^ 2-4x = 0[/tex]

To solve this equation we must factor:

1.- Take common factor x.

[tex]x(x-4) = 0[/tex]

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

[tex]x = 0[/tex] or [tex]x-4 = 0[/tex]

[tex]x = 0[/tex] or [tex]x = 4[/tex]

3.- The solutions are:

[tex]x = 0\\x = 4[/tex]
