k(x) * f(x)


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


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


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


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

________________________________


k(x) * g(x) * f(x)


g(x) * (k(x) * f(x))


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