1) (8n^3 - 2n^4)(3n^5)

= 24n^8 - 6n^9

= 6n^8 ( 4 - n) =====> n = 0 or n = 4

2) (5x^8 + 4x^4 + 2x^3 + 11x^2) 2x^2

= 10x^10 + 8x^6 + 4x^5 + 22x^4

= 2x^4 ( 5x^6 + 4x^2 + 2x + 11)

======> x = 0

3) d = 0 or d= 11/8 = 1.375

1) (8n^3-2n^4)(3n^5)

= **24n^8 - 6n^9**

2) (5x^8+4x^4+2x^3+11x^2)2x^2

=** 10x^10+8x^6+4x^5+22x^4**

3) (4d(8d-11))

= **32d^2-44d**

The instructions say to Simplify into Standard Form. Without knowing if there is = 0 the answers will be:

1. 6n^8 ( 4 - n)

2. 2x^4 ( 5x^6 + 4x^2 + 2x + 11)

3. 32d^2 - 44d
