just solved all of these ... will copy solutions

grouping ___ (-x^2y^2 + 4 y^2) + (x^4 - 4x^2)
factoring ___ -y^2(x^2 - 4) + x^2(x^2 - 4)
rearranging ___ (x^2 - y^2)(x^2 - 4)
factoring (again) ___ (x + y)(x - y)(x + 2)(x - 2) ___ difference of squares, twice


8t(t^2 - 10t + 25)
8t (t - 5)^2


-3b(k^2 - 3k + 2)
-3b (k - 2) (k - 1)
