Question

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 1

The answer is 10x² - 4x.

Explanation:

You have to apply Distributive Law,

`a(m + n) = am + an`

So for this question :

`2x(5x - 2)`

`= 2x(5x) + 2x( - 2)`

`= 10 {x}^(2) - 4x`
