-1, -3/4, -5/8, -1/20, 0

Step-by-step explanation:

-1/20 = -2/40

-5/8 = -25/40

-3/4 = -30/40

0 = 0/40

-1 = -40/40

- 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
