<PRE><B>Question 204997</B>
factor completely: 3x^2(4x^2+1)^8 + 64x^4(4x^2+1)^7 
------------------
There is a common factor in the two terms.
It is x^2(4x^2+1)^7
-----------------------------
So factor the two terms to get these two factors:
x^2(4x^2+1)^7[3(4x^2+1) + 64x^2]
---
Simplify the 2nd factor to get:
---
x^2(4x^2+1)^7[12x^2 + 3 + 64x^2]
----
x^2(4x^2+1)^7[76x^2+3]
---
[(4x^2+1)^7][76x^4+3x^2]
