Persamaan kuadrat diketahui x²-8x+6 Tentukan: 1. X1². X2 + X1 . X2² 2. X1³ . X2 + X1 . X2³ tolong yaa gan secepatnya beserta caranyaa

x^2 - 8x + 6
a=1
b=-8
c=6

x1 + x2 = -b/a = -(-8)/1 = 8
x1.x2 = c/a = 6/1 = 6

1.
x1.x2 ( x1 + x2) = 6×8 = 48

2.
(x1.x2)[(x1 + x2)^2 - 2x1.x2]
6(8^2 - 2×6)
6(64 - 12)
6(52)
312
