Answer:
x1 = 0
x2 = 3
Step-by-step explanation:
[tex] {x}^{2} - 3x = 0[/tex]
If that's the right equation we can now just simplify it a bit.
[tex]x \times x - 3 \times x = 0[/tex]
Cause now it becomes obvious that we can break out x and make it into a parenthesis:
[tex]x(x - 3) = 0[/tex]
And now there's two possibilities for what x could be. Either, x is 0:
[tex]0(0 - 3) = 0[/tex]
Or, the parenthesis is 0, which means that x is 3 (because 3-3=0) :
[tex]x(3 - 3) = 0[/tex]
So x has two answers:
x1 = 0
x2 = 3
At least I hope this was what you were looking for
