What is the product of -2x^3+x-5 and x^3-3x-4 (a) show your work (b) is the product of -2x^3+x-5 and x^3-3x-4 equal to the product of x^3-3x-4 and -2x^3+x-5? explain your answer

-2x³+ x-5x³-3x-4

Collect like terms by calculating the sum or difference of their coefficients.

-2x³-5x³ ---> -2-5x³

Calculate the sum or difference.

-7x³

x-3x

If a term doesn't have a coefficient, it is considered that the coefficient is 1.

1x-3x

Collect like terms by subtracting their coefficients.

1-3x

Calculate sum or difference. 

-2x

Final answer.

-7x³+-2x-4

No, the products are not equal because the product of the second equation is 9x³-3x+x-5.
