What is the fully simplified form of the expression (-16 x3y - 20 x2 y2 -12 x y3) ÷ 2xy? *Remember to factor each expression completely before dividing.

a
- 8x^2 - 10xy - 6y^2
b
- 8x^2y -10xy -6xy^2
c
- 16x^2 - 10xy - 12y^2
d
- 16x^3y - 10xy - 12xy^3

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
