Answer:
The answer is
<h2>( x - 4)( x + 16)</h2>
Step-by-step explanation:
x² + 12x - 64
To factorize the expression write 12x as a difference
That's
x² + 16x - 4x - 64
<u>Factor out x from the expression</u>
That's
x( x + 16) - 4x - 64
<u>Factor out - 4 from the expression</u>
That's
x( x + 16) - 4 ( x + 16)
<u>Factor out (x + 16) from the expression</u>
We have the final answer as
<h3>( x - 4)( x + 16)</h3>
