Since it is under 985,000, you would round it down. So your answer rounded to the nearest ten thousand would be 980,000

The given expression is

$2x^3-16x^2-40x=0$

We extract the common factor 2x.

$\begin{gathered} 2x(x^2-8x-20)=0 \\ 2x=0\rightarrow x=0 \\ x^2-8x-20=0 \end{gathered}$

The first solution is 0.

Now, we solve the quadratic expression. We have to find two numbers whose product 20 and whose difference is 8. Those numbers are 10 and 2.

$x^2-8x-20=(x-10)(x+2)$ <h2>Hence, the given expressions expressed, as factors, is</h2> $2x^3-16x^2-40x=x(x-10)(x+2)$

Well, you would need to do 195x4 and you would get 780, I believe. So 780 divided by 4 is 195.
