An expression is shown below: 2x^3 + 10x^2 − 4x^2y − 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)

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)

 the answer for letter A is: 2x(x²)+2x(5x)+2x(-2xy)+2x(-10y)
 the answer for letter B is: 2x(x²+5x-2xy-10y)
