jika suku banyak f(x):x+3 sisa 4 dan jika f(x): 2x-1 sisa 10. Tentukan sisa jika f(x):2x²+5x-3

F(x)= x+3 --> 4
F(x)= 2x-1 --> 10
F(x)= 2x^2+5x-3 --> ax+b
(2x-1) (x+3)
2x= 1 V x= -3
x= 1/2
cari a:
x=1/2 --> 1/2a+b = 4 |×2| 1a+b = 8
x=-3 --> -3a+b = 10 |×1| -3a+b= 10_
4a = 2
a = 2
cari b:
a+b= 4
3.(2)+b= 4
6+b= 4
b= 4-6
= -2
