**drwls**, Friday, January 4, 2008 at 1:18amWhat do you mean by "simplify?" Express in factor form?

6x^4 - 8 = 6(x^4 -4/3)

= 6[x^2 + sqrt(4/3)]{x^2 - sqrt(4/3)]

The last term in brackets fan be factored one more.

a²b - a² - 2b -2 = a^2(b-1) -2(b+1)

Those don't look any "simpler" than the original versions.
