(x+2) = 4
nilai x=-2 bersisa 4
ax+b = sisa
a(-2) + b = 4
-2a + b = 4 ...(1)

(2x-1) = 6
nilai x=1/2 bersisa 6
ax+b = sisa
a(1/2) + b = 6
(1/2)a + b = 6 ...(2)

Eliminasi pers. 1 dan 2

-2a + b = 4
(1/2)a + b = 6
____________-
(-5/2)a = -2
a = -2 / (-5/2)
a = -4/-5
a = 4/5

-2a + b = 4
-2(4/5) + b = 4
-8/5 + b = 4
b = 4 + 8/5
b = 28/5

sisa pembagian oleh 2x^2+3x-2
ax+b
(4/5)x + (28/5) = 0
________________ x 5
4x + 28 = 0
