Can someone please help me with this my teacher didn’t show me how to do this

The distance on the y-axis (not sure if thats how you say it :| ) is 8, and the distance between the x-axis (again not sure thats the correct term) is 6

im not a genius, but I hope this helps :D

(there is a gragh with the points)

- 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
