soal mtk cara cariknya

jawab

f(x) = 4x³ +10x²+ 4x - 3
p(x)= 2x+ 3
2x + 3 =0
x = - 3/2
cara horner

.......|.4......10......4.......-3
-3/2.|.........-6......-6......+3
.........4.......4.......-2......0
hasil bagi (4x² + 4x - 2)/2 = 2x² + 2x - 1

17)
f(x)=  x⁵ - 3x - 8
p(x) = x² - x - 2
p(x) = 0
x² - x - 2 = 0
(x - 2)(x +1) =0
x = 2 atau x = - 1

sisa  s(x) = ax + b
sisa = nilai fungsi
s(x) = f(x)

s(2) = f(2)
2a + b = 2⁵ -3(2)  - 8
2a + b = 18 ..(i)

s(-1) = f(-1)
-a + b = (-1)⁵ - 3(-1) - 8
-a + b = -6 ..(ii)

(i) dan (ii)
2a  + b =  18
- a + b = - 6 ||(-)
3a = 24
a= 8

-a  + b = - 6
b = a -6
b = 8 - 6
b = 2

s(x) = 8x + 2
