SOLUTION: (x-4)(2x^2+4)+(x+4)(x^3-1)-(x^2-x-1) The question ask to combind terms and multiply....Here is my result????? (x*2x^2)+(x*4)+(-4*2X^2)+(-4*4)= 2x^3+4x-8x^2- 16 = -10x

SOLUTION: (x-4)(2x^2+4)+(x+4)(x^3-1)-(x^2-x-1) The question ask to combind terms and multiply....Here is my result????? (x2x^2)+(x4)+(-42X^2)+(-44)= 2x^3+4x-8x^2- 16 = -10x

Question 157458: (x-4)(2x^2+4)+(x+4)(x^3-1)-(x^2-x-1)

The question ask to combind terms and multiply....Here is my result?????

(x*2x^2)+(x*4)+(-4*2X^2)+(-4*4)= 2x^3+4x-8x^2- 16
= -10x^5-16

(x*x^4)+(x*-1)+(4*x^3)+(4*-1)= x^4-x+4x^3-4
= 4x^6-4

x^2-x-1
= x-1

(-10x^5-16)+(4x^6-4)-(x-1)

= -7x^10-19
