Jawab:
f(x) = x(x + 1)(x² - 2)
f(x) = (x² + x)(x² - 2)
f(x) = x^4 + x³ - 2x² - 2x
g(x) = x³ - 3x² - 2x + 3
(f + g)(x)
= x^4 + x³ - 2x² - 2x + x³ - 3x² - 2x + 3
= x^4 + 2x³ - 5x² - 4x + 3
cara horner
[tex]\frac{(f + g)(x)}{x + 1} = \frac{x^{4} + 2x^{3} - 5x^{2} - 4x + 3}{x + 1}[/tex]
-1 ║ 1 2 -5 -4 3
║ -1 -1 6 -2
________________
1 1 -6 2 1
sehingga diperoleh s = 1 dan h(x) = x³ + x² - 6x + 2
nilai h(s) = 1³ + 1² - 6(1) + 2 = 1 + 1 - 6 + 2 = 2
sekian jawaban dari saya
semoga bermanfaat
