Verified answer
F(x)=x³+nx²+2x+3x+1=0, sisa 9
x= -1
f(-1)=(-1)³+n(-1)²+2(-1)+3
9=n
x+2=0
x=-2
f(-2)=(-2)³+(9)(-2)²+2(-2)+3
sisa= 27
Verified answer
Jika f(x) = x³ + nx² + 2x + 3 dibagi (x+1) sisanya 9artinya adalah
f(x) = (x+1)H(x) + 9
ini berarti
f(-1) = 0 + 9
→ f(-1) = 9 ←
f(-1) = (-1)³ + n(-1)² + 2(-1) + 3 = 9
n = 9 ✔️
jadi jika f(x) dibagi (x+2) maka sisa pembagiannya adalah f(-2)
= (-2)³ + 9(-2)² + 2(-2) + 3
= 27 ✔️
semoga jelas dan membantu
