What is the simplest form of the expression -2x^2(x+5)+x(2x^2-10x)+x

Softa [21]

For this case we have the following expression:
-2x ^ 2 (x + 5) + x (2x ^ 2-10x) + x
Rewriting we have:
-2x ^ 3 - 10x ^ 2 + 2x ^ 3 - 10x ^ 2 + x
Grouping terms with the same exponent:
x ^ 3 (-2 + 2) + x ^ 2 (-10 - 10) + x
-20x ^ 2 + x
Rewriting:
x (-20x + 1)
Answer:
The simple form of the expression is:
x (-20x + 1)

To find the fraction of the group's video games is either at Jerome house or Mario house.

Between two they have = $J+M$ = $\frac{1}{4} + \frac{2}{5} = \frac{5+8}{20} =\frac{13}{20}$ of the group's video games.
