Seorang mempunyai persediaan rumput yang cukup untuk 7 ekor kuda selama 78 hari. Berapa harikah persediaan itu cukup untuk 21 ekor kuda

x 3 + 13 x 2 + 32 x + 20 = x 3 + x 2 + 12 x 2 + 12 x + 20 x + 20 = = x 2 ( x + 1 ) + 12 x ( x + 1 ) + 20 ( x + 1 ) = ( x + 1 ) ( x 2 + 12 x + 20 ) = = ( x + 1 ) [( x 2 + 10 x + 2 x + 20 )] = ( x + 1 ) [ x ( x + 10 ) + 2 ( x + 10 ))] = = ( x + 1 ) ( x + 2 ) ( x + 10 )

To factor the equation x 3 + 13 x 2 + 32 x + 20 , we first identify a root, which is x = − 1 . This allows us to factor it as ( x + 1 ) ( x 2 + 12 x + 20 ) , which further factors to ( x + 1 ) ( x + 10 ) ( x + 2 ) .
