hasil kali dua bilangan genap berurutan adalah 224 tentukan bilangan bilangan itu

<p>Saya bantu jawab ya.....</p><p>&nbsp;</p><p>Misalkan bilangan genap pertama = a, maka bilangan genap kedua = a + 2</p><p>sehingga :</p><p>a x (a + 2) = 224</p><p>a² + 2a = &nbsp;224</p><p>a² + 2a - 224 = 0</p><p>(a + 16)(a - 14) = 0</p><p>a = -16 atau a = 14</p><p>&nbsp;</p><p>Kita ambil bilangan pertama a = 14 maka&nbsp;</p><p>Bilangan kedua = a + 2&nbsp;</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 14 + 2&nbsp;</p><p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= 16</p><p>Jadi, bilangan tersebut adalah<strong> 14 </strong>dan <strong>16</strong></p><p>&nbsp;</p>
