b. 2x-5
c. x pngkt 2 +6x+11 sisa 15
d. 3x pngkt 2 -10x + 15 sisa -24
a. no a keak nya kurng pas.
keak nya yg a ni slh soal.
b. (3x+5)(x-2)
(2x-5)(x+2)/(x+2) = 2x-5
untuk pangkat tiga
untuk mencari hasil bagi lebih mudah pake horner
2 7 -14 -40
5/2 5 30 -40
2 12 -16 0
hasilbagi = 2x²+12x-6
3 -4 -5 6
-2 6 8 -6
-3 -4 3 0
(x-1)² -1 -10 = (x-1)² =11
(x-1) = √11
x=1+√11
x=1-√11
a. (x+1+√11)(x+1-√11)
b. (3x-5)(x-2)
