suku banyak 8x^3-18x^2+px+30 habis dibagi ol3h (2x-3). Nilai p = ... tolong pakai cara jalannya

habis dibagi (2x - 3)
2x - 3 = 0
x = 3/2

substitusi kan x = 3/2 ke persamaan

18x² + px + 30 = 0
18(3/2)² + (3/2)p + 30 = 0
18 . 9/4 + 3/2 p + 30 = 0
3/2 p = -30 - 81/2
3/2 p = (-60 - 81)/2
3p = -141
p = -141/3
p = -47
