Question 430027: • Simplify each expression. Show all the steps of your simplification.
a. (n2 – 5n + 3)(n2 + n – 1)
b. (4a3b2)3 (3ab4)2

I have half of the first one done but i know i am missing the explination of some steps, i forget how to do the steps in depth i just do the problem without showing most of my work, pelase help!

a. (n2 – 5n + 3)(n2 + n – 1)
---
= n^2(n^2+n-1) -5n(n^2+n-1) + 3(n^2+n-1)
-----
= n^4+n^3+n^2 - 5n^3-5n^2+5n + 3n^2+3n-3
----
= n^4+n^3-n^2+8n-3
=================================

b. (4a3b2)^3 (3ab4)^2
----
= (64a^12b^6)(9a^2b^8)
---
= 576a^14b^14
