Question

Tolong bantu...pakai cara, no 6 aja

Answer 1

Pake teorema sisa
f(x) = s(x)
f(3) = 18
2(3^3) + 3(3^2) + 3a - 3 = 18
54 + 27 + 3a - 3 = 18
3a + 78 = 18
3a = -60
a = - 20

hasilnya pake horner
x=3. 2. 3. -20. -3
| 6. 27. 21
------------------------
2. 9. 7. 18
hasil baginya = 2x^2 + 9x + 7
