Kuis 12 Persamaan Math Matriks Suatu Perusahaan

10x + 13x - 13 = 0

(2x - 1)(5x + 3) = 0

Complete Square:

10x + 13x - 3 = 10  

10x + 13x - 13 = 0

10(x + 13/20x - 13/10) = 0

10(x + 13/20) - 169/4 = 0

10(x + 13/20) = 169/4

(X + 13/20) = 169/40

Penyelesaian Persamaan:

(X + 13/20) = kurang lebih (akar kuadrat 169/40)
