Answer
(6x3 - 5x + 10) (4 - 3x2)
= 4 (6x3 - 5x + 10) - 3x2 (6x3 - 5x + 10)
= 24x3 - 20x + 40 - 18x(3+2) + 15x(1+2) - 30x2
= 24x3 - 20x + 40 - 18x5 + 15x3 - 30x2
= - 18x5 + 24x3 + 15x3 - 30x2 - 20x + 40
= - 18x5 + 39x3 - 30x2 - 20x + 40
Hence, (6x3 - 5x + 10) x (4 - 3x2) = - 18x5 + 39x3 - 30x2 - 20x + 40
