Akar akar persamaan x2 - 18x + 3m + 12=0 adalah alfa dan beta. jika alfa = 5 beta. Maka nilai m adalah ?

betaljemur Persamaannya x^2-18x+13m+12=0

misal alfa = X1 dan beta = X2 *biar gampang

X1=5(X2)

X1+X2=18
5X2+X2=18
6X2=18
X2=18/6
X2=3

X1=5(3)
X1=15

sekarang mencari m

X1.X2=3m+12
15.3= 3m+12
45=3m+12
33=3m
m=33/3
m=11, jadi m nya 11
