Use these patterns to factor polynomials that are sums and differences of cubes.
a^3 + b^3 = (a+b)(a^2-ab+b^2)
d)2u^3 + 16V^3
e)d^5 + f^3
f) w^6 -1
2. if the sum of two numbers is 6 and the sum of their cubes is 18, what's the sum of their squares?
3. use synthetic division to find (x^2 + 4) / (s - 2i)
