Question 171529
I think you tried typing this:

25x(x^3 + 5)(2 - 6)

Simplify section by section.

We apply the distributive rule to remove the parentheses.

(25x^4 + 125x)(-4)

We now use the distributive rule again.

I will place (-4) on the left side of the quantity (25x^4 + 125x)for easy reading.

(-4)(25x^4 + 125x)= -100x^4 - 500x

You can factor (-100x^4 - 500x) to simplify further.

I'll let you that.

If you cannot, write back.
