2x^8+2x^5-32x^4-32x

Question

with steps and answer please 

Answer 1

Assuming that "z" should be "x", we have:

 

2x⁸ + 2x⁵ - 32x⁴ - 32x

 

= 2x⁵(x³ + 1) - 32x(x³ + 1)

 

= (2x⁵ - 32x)(x³ + 1)

 

= 2x(x⁴ - 16)(x³ + 1)

 

= 2x(x² + 4)(x² - 4)(x + 1)(x² - x + 1)

 

= 2x(x² + 4)(x + 2)(x - 2)(x + 1)(x² - x + 1)

Answer 2

Is this a factoring problem? If so, only the factor "2" is shared in common, resulting in:

2(z^8 + x^5 - 16x^4 - 16x)

Can you clarify the problem?
