Question

What is the factored form of x2 + 12x – 64?

Answer 1

The answer is

( x - 4)( x + 16)

Explanation:

x² + 12x - 64

To factorize the expression write 12x as a difference

That's

x² + 16x - 4x - 64

Factor out x from the expression

That's

x( x + 16) - 4x - 64

Factor out - 4 from the expression

That's

x( x + 16) - 4 ( x + 16)

Factor out (x + 16) from the expression

We have the final answer as

( x - 4)( x + 16)

Hope this helps you
