Factor each of following expressions

x (4th power) - x (3rd power) - 6x (2nd power

(a-b)(2nd power) - (a 2nd power + b) 2nd power

1. 0
2. 1
1. x^2(x^2-x-6)
= x^2 (x-3)(x+2)

2. (a-b)^2 - (a^2+b)^2

a^2-2ab+b^2 -(a^4 + 2 a^2 b + b^2)

-a^4 - 2 a^2 b - 2 a b

-a (a^3 + 2 a b + 2 b)

I can not see more to do
