Thread: Simplifying an expression

Ok, I need to know how to solve, or if someone could just help me get started on this problem...


(b^2 + 4 b + 16)/(b^3 - 64)


Thanks!

Note that:
a^3 - b^3 = (a-b)(a^2+ab+b^2)

and that 64 = 4^3

can you finish?

You are not solving anything here. There is no equation to solve. You are simplifying an expression.
