Question

Which answer is correct

Answer 1

Answer: B

$x^{3} (4x-1) (4x-1)$

Step-by-step explanation:

Start with the given equation.

$16^5 - 3x^3$

Start out by factoring the GCF.  x^3 is the GCF of both terms:

$x^3 (16x^2 - 1)$

Use the different of squares method.:

$a^2-b^2=(a+b)(a-b)$

$a^2=16\\b^2=1$

Substituted the equations:

$16^2-1^2=(a+b)(a-b)$

Factor:

 $16x^2-1^2=(4x+1)(4x-1)$

Add GCF to the factor equation:

$x^3(4x+1)(4x-1)$
