Answer 2

Step-by-step explanation:

*Each term of the first expression should multiply the second expression.

$(-2x^{3} + x-5) (x^{3} -3x-4)\\=-2x^{3} (x^{3} -3x-4) +x (x^{3} -3x-4) -5(x^{3} -3x-4)\\=-2x^{6} +6x^{4} + 8x^{3} +x^{4} - 3x^{2}-4x - 5x^{3}+15x+20\\=-2x^{6}+7x^{4}+3x^{3}-3x^{2}+11x+20$

*While multiplying note that if both have same signs the answer will come in +.

*While multiplying note that if both have different signs the answer will come in -.
