( 6 x + 9 ) ( x ^ 2 - 4 x + 5 ) =
6 x * x ^ 2 + 9 * x ^ 2 + 6 x * ( - 4 x ) + 9 * ( - 4 x ) + 6 x * 5 + 9 * 5 =
6 x ^ 3 + 9 x ^ 2 - 24 x ^ 2 - 36 x + 30 x + 45 =
6 x ^ 3 - 15 x ^ 2 - 6 x + 45 =
3 ( 2 x ^ 2 - 5 x - 2 x + 15 )
6 x * x ^ 2 + 9 * x ^ 2 + 6 x * ( - 4 x ) + 9 * ( - 4 x ) + 6 x * 5 + 9 * 5 =
6 x ^ 3 + 9 x ^ 2 - 24 x ^ 2 - 36 x + 30 x + 45 =
6 x ^ 3 - 15 x ^ 2 - 6 x + 45 =
3 ( 2 x ^ 2 - 5 x - 2 x + 15 )
