Question

x² - 4x+1 (factorize)​

Answer 1

Step-by-step explanation:

x² - 4x+1

D = b²-4av

D = b²-4av= ( -4)² - 4 × 1 × (-1)

D = b²-4av= ( -4)² - 4 × 1 × (-1)= 16 + 4

D = b²-4av= ( -4)² - 4 × 1 × (-1)= 16 + 4= 20

D = b²-4av= ( -4)² - 4 × 1 × (-1)= 16 + 4= 20X = -b ± √D/ 2a

D = b²-4av= ( -4)² - 4 × 1 × (-1)= 16 + 4= 20X = -b ± √D/ 2a= -(-4) ± √20/2×1

D = b²-4av= ( -4)² - 4 × 1 × (-1)= 16 + 4= 20X = -b ± √D/ 2a= -(-4) ± √20/2×1= 4 ± 2 √5/2
