Hi there!

Let us solve the equation step-for-step.

Simplify both sides of the equation. It would look like this -

x² - 7x = 0

Then, we factor the left side of the equation. It will look like what you started with.

x (x - 7) = 0

Finally, set factors equal to zero.

x = 0 or x - 7 = 0

x can equal 7 or 0. It does not matter because both answers will give you the same outcome.

Hope this helps! :D
