Ingat rumus determinan fungsi kuadrat yaitu :
Maka, Kita kembali jawab soalnya.
⏩Nomor (1) :
»8x² + 7x + 10 = 0
Didapatkan nilai² a, b, dan c yaitu :
- a = 8 | b = 7 | c = 10
Maka, nilai determinannya adalah
- D = b² - 4ac
- D = 7² - 4(8)(10)
- D = 49 - 4(80)
- D = 49 - 320
- D = -271✅
⏩Nomor (2) ;
»2x² + 10x + 10 = 5
»2x² + 10x + 10 - 5 = 0
»2x² + 10x + 5 = 0
Didapatkan nilai² a, b, dan c yaitu :
- a = 2 | b = 10 | c = 5
Maka, nilai determinannya adalah
- D = b² - 4ac
- D = 10² - 4(2)(5)
- D = 100 - 4(10)
- D = 100 - 40
- D = 60✅
