X²-(k+1)x+8=0 nilai k =
Jawaban Terkonfirmasi
X² - ( k + 1 ) x + 8 = 0
( x - 4 ) ( x - 2 ) = 0
x² - 2x - 4x + 8 = 0
x² - 6x + 8 = 0
jadi :
k + 1 = 6
k = 6 - 1
k = 5
X²-(k+1)x+8=0 nilai k =
X² - ( k + 1 ) x + 8 = 0
( x - 4 ) ( x - 2 ) = 0
x² - 2x - 4x + 8 = 0
x² - 6x + 8 = 0
jadi :
k + 1 = 6
k = 6 - 1
k = 5
