Jawaban:
HP : {5 + √53 / 2, 5 - √53 / 2}.
Penjelasan dengan langkah-langkah:
x = (-b ± √(b² - 4ac)) / (2a)
a = 1, b = -5, dan c = -7.
x = (5 ± √((-5)² - 4(1)(-7))) / (2(1))
x = (5 ± √(25 + 28)) / 2
x = (5 ± √53) / 2
Himpunan Penyelesaian :
x1 = (5 + √53) / 2
x2 = (5 - √53) / 2
HP : {(5 + √53) / 2, (5 - √53) / 2}.
