a.) a 10 ml pipette.
b.) a 100 ml graduated cylinder.
c.) a 1 ml pipette (used 10 times in a row).
d.) a 100 ml beaker.
e.) all of these would be equally accurate.

- 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
