Answer: A. 2x(x²)+2x(5x)+2x(-2xy)+2x(-10y)
B. 2x(x²+5x-2xy-10y)
Step-by-step explanation:
note: x*x means x times x
remember distributive and reverse it
ab+ac=a(b+c)
a is gcf
factor each
2x³=2*x*x*x
10x²=2*5*x*x
4x²y=2*2*x*x*y
20xy=2*2*5*x*y
gcf=2*x or 2x
2x³+10x²-4x²y-20xy=
2x(x²)+2x(5x)+2x(-2xy)+2x(-10y)=
2x(x²+5x-2xy-10y)
6239/10,000 or 6239/10^4
Hope I helped.
