Jawab:
Penjelasan dengan langkah-langkah:
faktorkanlah dan tentukan akar-akar persamaan kuadratnya dari
1. x² -6x + 5 = 0
2. x² + 8x + 15 = 0
3. x² -7x + 10 = 0
1. x² -6x + 5 = 0
(x - 5)(x - 1) = 0
x - 5 = 0 | x -1 = 0
x = 5 | x = 1
2. x² + 8x + 15 = 0
(x + 5) (x + 3) = 0
x + 5 = 0 | x + 3 = 0
x = -5 | x = -3
3. x² -7x + 10 = 0
(x - 5)(x - 2) = 0
x - 5 = 0 | x -2 = 0
x = 5 | x = 2
