<h2>♪Answer : </h2>

Ingat rumus determinan fungsi kuadrat yaitu :

\longmapsto\boxed{\sf{D = b^2 - 4ac}}

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✅
