Iwould really like some . i don't understand how the hcf/gcf of −8y and 40 is 8 and how the hcf for −5y and −25 is -5 and not 5. 5 is a factor of both of the terms and it is greater than -5 so why is it not 5? can i explain this to me? you.

- 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
