Question

Persamaan kuadrat yang akarnya -5 dan -2 adalah...

Answer 1

 α = -5
β = -2

α+β = (-5) + (-2) = -7
α.β = (-5) x (-2) = 10

persamaan kuadrat:
x² - (α+β)x + (α.β) = 0
x² - (-7)x + 10 = 0
x² + 7x + 10 = 0

semoga membantu :)

Answer 2

X = -5
x + 5 = 0

x = -2
x + 2 = 0

Persamaan
(x + 5) (x + 2) = 0
x² + 7x +10 = 0
