5 0

Answer:

10x^2-4x

Step-by-step explanation:

We will have to open the bracket first

So let's solve

2x(5x-2)

10x^2-4x

Since we are not asked to solve further so we will have to leave he final answer as 10x^2-4x

But in the case where a certain value is given to substitute for x we will have to solve further

Plz help, I will mark brainliest
ad-work [718]
X > 10 Because if you remove the parenthesis and distribute 4 through the parentheses - 8x + 8 + 12. Then you add 8 and 12 which equals 20. Then you move the constant to the right-hand side and change its sign. You calculate 100 - 20 which give you 80 and divide then which gives you 10.

Hopefully this helps! <3
