Thanks I copied it incorrectly. It should read 4q2 + 27r4. Thanks for your help. Also to factor 2a3 - 128, is this prime?

Hi jay1,

You still can't do anything with $\displaystyle 4q^2+27r^4$

And for $\displaystyle 2a^3-128$, first factor out a 2.

$\displaystyle 2(a^3-64)$ and recognize that $\displaystyle a^3-64$ is the difference of two cubes. You should know how to handle that one, don't you?

$\displaystyle 2(a^3-4^3)=$ - Jan 13th 2010, 11:12 AMjay1
Masters, 2 (a-4)3 ??? (the 3 being an exponent)
