Syahbanazackigo

Step-by-step explanation:

2x² - 9x + 2 = -1

2x² - 9x + 3 = 0

D = b² - 4ac

D = (-9)² - 4.2.3

D = 81 - 24

D = 57

D > 0 , so there are two real roots

Option → C

2x² - 9x + 2 = -1

2x² - 9x + 2 + 1 = 0

2x² - 9x + 3 = 0

  • a = 2
  • b = -9
  • c = 3

Soo :

D = b² - 4ac

D = (-9)² - 4(2)(3)

D = 81 - 4(6)

D = 81 - 24

D = 57

Option (C.)
