k(x) \times f(x)

(2x + 5) \times (x - 1)

2 x(x - 1) + 5(x - 1)

({2 x }^{2}  - 2x) + (5x - 5)

{2x}^{2}  - 3x - 5

________________________________

k(x) \times g(x) \times f(x)

g(x) \times (k(x) \times f(x))

({6x   }^{2}  - 4x +  {3x}^{4} ) \times ( {2x}^{2}  - 3x - 5)

{6x}^{2}  ( {2x}^{2}  - 3x - 5) - 4x ( {2x}^{2}  - 3x - 5) +  {3x}^{4}  ( {2x}^{2}  - 3x - 5)

12 {x}^{4}  - 18 {x}^{3}  - 30 {x}^{2}  -  {8x}^{3}  - 12 {x}^{2}  - 20x +  {6x}^{6}  - 9x {}^{5}  -  {15x}^{4}
