Determine whether x 2 - 16 is a difference of two squares. If so, choose the correct factorization.

yes; (x - 4) 2
yes; (x + 4) (x - 4)
yes; (x + 4) 2
No

Yes:

Step-by-step explanation:

Factoring

Converting a sum or subtraction of terms into a product is calling factoring. The expression

can be written as

It's a difference of two squares. It can be factored as the sum by the difference of two factors:

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x

one fourth of 9% = 2.25%

gavin is correct in saying : the equivalent quarterly interest rate would be

2.25%.
