Q: f (x) = 2x² – 5x + 2 का सही गुणनखंड चुनें।
  • A. x – 2
  • B. x – 3
  • C. x – 4
  • D. x –5
Correct Answer: Option A - f (x) = 2x² – 5x + 2 = 2x² – 4x – x + 2 = 2x (x – 2) – 1 (x – 2) = (2x – 1) (x – 2)
A. f (x) = 2x² – 5x + 2 = 2x² – 4x – x + 2 = 2x (x – 2) – 1 (x – 2) = (2x – 1) (x – 2)

Explanations:

f (x) = 2x² – 5x + 2 = 2x² – 4x – x + 2 = 2x (x – 2) – 1 (x – 2) = (2x – 1) (x – 2)
