Question 281400
There are a lot of different ways to factor out something sometimes it may be hard to remember. In your example:

{{{5x^2 - 2x = 0}}}

You can factor using greatest common multiple. The greatest common multiple of {{{5x^2}}}, and {{{2x}}} is {{{x}}}

Therefore you can take out an x like this:

{{{5x^2 - 2x = x(5x-2)}}}

Now that you have it factored, you have to set both of them equaling to 0. The first one is easy:

{{{x = 0}}}

second one requires a little more algebra.

{{{5x - 2 = 0}}}
{{{5x = 2}}} and finally
{{{x = 2/5}}}

Those are both your answers!
