Please help An expression is shown below:

2x3 + 10x2 − 4x2y − 20xy

Part A: Rewrite the expression so the GCF is factored completely. (4 points)

Part B: Rewrite the expression completely factored. Show the steps of your work. (6 points)

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)

idk

step-by-step explanation:

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
