Suku banyak f(x) jika di bagi (x-2) sisanya 24 dan f(x) dibagi (x+5) sisanya 10 . apabila f(x) tersebut dibagi (x²+3x-10) sisanya adalah?

Misal f(x) : (x^2 + 3x – 10) = (x + 5)(x – 2) bersisa ax + b
f(x) : (x – 2) bersisa 24 => S(2) = 24 => 2a + b = 24
f(x) : (x + 5) bersisa 10 => S(-5) = 10 => -5a + b = 10
2a + b = 24
-5a + b = 10
—————– –
7a = 14 => a = 2

2a + b = 24
=> 2(2) + b = 24
=> b = 20
jd sisanya ax + b = 2x + 20
