Akar = - 3maka x = - 3 atau x + 3 = 0 ............... (x + 3)
akar = 1/2
maka x = 1/2 atau 2x = 1 atau 2x - 1 = 0 ...........(2x - 1)
Persamaan kuadrat yang faktornya terdiri dari (x + 3) dan (2x - 1) adalah
= (x + 3) (2x - 1)
= (x . 2x) + (x . (-1)) + (3 . 2x) + (3 . (-1))
= 2x² - x + 6x - 3
= 2x² + 5x - 3
