Hitung jumlah akar-akar dari persamaan kuadrat: x^2 - 4x + 4 = 0
Dalam persamaan x^2 - 4x + 4 = 0, Diskriminan = (-4)^2 - 4*1*4 = 16. Karena Diskriminan > 0, maka terdapat dua akar berbeda.
Dalam persamaan x^2 - 4x + 4 = 0, Diskriminan = (-4)^2 - 4*1*4 = 0. Karena Diskriminan = 0, maka tidak ada akar yang valid.
Dalam persamaan x^2 - 4x + 4 = 0, Diskriminan = (-4)^2 - 4*1*4 = 0. Karena Diskriminan = 0, maka terdapat satu akar ganda.
Dalam persamaan x^2 - 4x + 4 = 0, Diskriminan = (-4)^2 - 4*1*4 = 16. Karena Diskriminan > 0, maka terdapat dua akar kompleks.
