jika suku banyak 2x^3 + x^2 + 4x + 4 dan 2x^3 + x^2 + 2x + a dibagi dengan 2x - 3 bersisa sama maka nilai a=

Pembagian suku banyak

f(x) = 2x³ +x² + 4x + 4
g(x)= 2x³+x² + 2x + a
pembagi (2x-3) =0 --> x = 3/2

sisa sama f(3/2) = g(3/2)
2x³+x²+ 4x + 4 = 2x³+x² + 2x + a
4x +4 = 2x+a
a = 4x-2x + 4
a = 2x + 4
x= 3/2
a = 2(3/2) + 4
a= 3+4
a = 7
