Answer please! I have been "getting" the correct answer, as far as I know. The answer which I got was 10x^2 - 4x. But I don't see how it's incorrect. PLEASE HELP!

Answer:
The answer is 10x² - 4x.
Step-by-step explanation:
You have to apply Distributive Law,
[tex]a(m + n) = am + an[/tex]
So for this question :
[tex]2x(5x - 2)[/tex]
[tex] = 2x(5x) + 2x( - 2)[/tex]
[tex] = 10 {x}^{2} - 4x[/tex]
