Sisa f(x) oleh -x^2+5x-6 misalny ax + b
f(3) = -2x27 + 4x9 + 3 + 7 = 3a + b
-8 = 3a+b ___(1)
f(2) = -2x8 + 4x4 + 2 + 7 = 2a + b
9 = 2a + b ___(2)
Eliminasi b dari persamaan (1) dan (2)
-17 = a
Substitusi a=-17 ke persamaan (1) atau (2)
-8 = 3x(-17) +b
b=43
Jd sisanya adalah -17x + 43
p(x)= -x² + 5x - 6 => (x-6)(-x-1)
h(x)= -2x²+6x-7
s(x)= -7
