Question

Jika suku banyak f(x) = 3x³ - 16x + a habis dibagi (x-3), maka nilai a =​

sertai langkah pengerjaan​

Answer 1

Penjelasan dengan langkah-langkah:

x - 3 = 0

x = 0 + 3

x = 3

f(x) = 3x³ - 16x + a

f(3) = 3(3)³ - 16(3) + a

0 = 81 - 48 + a

0 = 33 + a

33 + a = 0

a = -33

Answer 2

Penjelasan dengan langkah-langkah:

POLINOMIAL

f(x) = 3x³ - 16x + a

x – 3 = 0

x = 3

f(3) = 0

3(3)³ – 16(3) + a = 0

a = 3(16) – 3(27)

a = 3(16 – 27)

a = 3 × (–11)

a = – 33 ✔
