Tentukan hasil bagi dan sisa jika: b. 4x³ - 39x + 11 dibagi x - 3

<p>Jawaban yang benar adalah 4x² + 12x - 3 dan 2</p><p>&nbsp;</p><p>Kita dapat mencari hasil bagi dan sisa dengan pembagian bersusun seperti berikut</p><p>&nbsp;</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 4x² + 12x - 3</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;-------------------</p><p>x - 3 / &nbsp;4x³ - 39x + 11</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;4x³ - 12x²&nbsp;</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;----------------- -</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 12x² - 39x + 11</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 12x² - 36x</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ------------------- -</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;-3x + 11</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;-3x + 9</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;----------- -</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 2</p><p>&nbsp;</p><p>Sehingga diperoleh</p><p>hasil bagi = 4x² + 12x - 3</p><p>sisa = 2</p><p>&nbsp;</p><p>Jadi, hasil bagi dan sisa adalah 4x² + 12x - 3 dan 2</p>
