SOLUTION: Evaluate the Polynomial x^3+2x^2+5x-1 when x=-2 This is how I did it: -2x^3+2.-2^2+5.-2-1 -2x^3=2.4-10-1 -2x^3+8-10-1 -2x^3-2-1 -2x^3-3 What is 3(x^2)^3 times (-2x^5)^3

Question 31321: Evaluate the Polynomial x^3+2x^2+5x-1 when x=-2
This is how I did it:
-2x^3+2.-2^2+5.-2-1
-2x^3=2.4-10-1
-2x^3+8-10-1
-2x^3-2-1
-2x^3-3
What is 3(x^2)^3 times (-2x^5)^3
Thanks in advance!
