Question

differeniate:
V(x)=(3x^3 + 5)(x^4-3x)

Answer 1

i got 12x^6+9x^5-16x^3-15.. the book tells me otherwise please tell me how you got your answers

Answer 2

If you multiply the 2 polynomials, you'll get 3x^7 + other stuff.... and the derivate of 3x^7 is not 12x^6.

Answer 3

its 21x^6 - 16x^3 -15 is the final solution

Answer 4

gimme a medal and become a fan if u like this answer

Answer 5

"its 21x^6 - 16x^3 -15 is the final solution"
