Which polynomial is a difference of squares?
Svetllana [295]

<u>Answer</u>

D.25x2 – 36


<u>Explanation</u>

A. x² – 16x + 64

product = 64

sum = -16

factors: -8 and -8

x² – 16x + 64  = x² - 8x - 8x + 64

                       = x(x - 8) - 8(x - 8)

                        = (x - 8)(x-8) = (x-8)²      ⇒ Not a difference of squares


B.x² + 4 = (x² + 2²) ⇒ Not a difference of squares


C.9x² – x – 36

product = - 324

sum = -1

Factors: none

9x² – x – 36  ⇒ Has no perfect roots.


D.25x² – 36

25x² – 36 = (5x)² - 6²   ⇒ This is the difference of squares.
