Temukan himpunan penyelesaian dari persamaan kuadrat x²+7x+10=0!
![]()
Jawaban:
x² + 7x + 10 = 0
(x + 5) (x + 2) = 0
x = -5 atau x = -2
Hp = {-5 , -2}
Penjelasan dengan langkah-langkah:
x² + 7x + 10 = 0
x = -b ±√b² - 4ac/2a
x = -7 ±√7² - 4(1)(10)/2(1)
x = -7 ±√49 - 40/2
x = -7 ±√9/2
x = -7 ± 3/2
x¹ = -7 + 3/2
x¹ = -4/2
x¹ = -2
x² = -7 -3/2
x² = -10/2
x² = -5
HP = {-5, - 2}
