Tentukan hasil bagi dan sisa jika: e. 4x³ + 6x² - 1 dibagi 2x + 1

<p>Jawaban yang benar adalah 2x² + 2x - 1 dan 0</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; &nbsp;2x² + 2x - 1</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;-----------</p><p>2x+1 / 4x³ + 6x² - 1</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;4x³ + 2x²</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;----------- -</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 4x² - 1</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 4x² + 2x</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ----------- -</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;-2x - 1</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;-2x - 1</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;-------- -</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 0</p><p>&nbsp;</p><p>Sehingga diperoleh</p><p>hasil bagi = 2x² + 2x - 1</p><p>sisa = 0</p><p>&nbsp;</p><p>Jadi, hasil bagi dan sisa adalah 2x² + 2x - 1 dan 0</p>
