How do I factor: x to the third minus 3x squared plus 4x minus 2
Nataliya [291]

Answer:

(x² − 2x + 2) (x − 1)

Step-by-step explanation:

Use grouping.

x³ − 3x² + 4x − 2

x³ − 3x² + 2x + 2x − 2

x (x² − 3x + 2) + 2 (x − 1)

x (x − 2) (x − 1) + 2 (x − 1)

(x (x − 2) + 2) (x − 1)

(x² − 2x + 2) (x − 1)
