jika (b - 3) (4+2/b) = 0, maka b = ... bantu guys

(B-3)(4+2/b) = 0
4b-10+6/b = 0
Samakan penyebutnya :
4b²-10b+6 = 0 × b
4b²-10b+6 = 0
(4b-6)(b-1) = 0

b = 6/4 dan b= 1

Semoga membantu, kalau bener jadikan terbaik ya. Makasih

(b - 3)(4 + 2/b) = 0
(b - 3) = 0 atau (4 + 2/b) = 0
b = 3 ................... 2/b = -4
.............................. 2 = -4b
.............................. b = 2/-4 = -1/2
Jadi b = -1/2 atau b = 3
