Answer 5

Ok..

Answer 6

2(x−2)(x2+2x+4)

Answer 7

\[ 2x^3-16 = 2 [ x^3-8] = 2[x^3-(2)^3] \]Did you understood these steps?

Answer 8

\[2[x^3-2^3]= 2(x-3)(x^2+2x+2^2) =2(x-3)(x^2+2x+4)\]

Answer 10

@dpasingh yes what about this one factor
9z^2-6z-8

Answer 11

\[9z^2-6z-8 = 9z^2-12z+6z-8= 3z(3z-4)+2(3z-4)= (3z+2)(3z-4)\] are the required factors of the given expression.
