Question

Can anyone give me an example of binomials being a difference of squares?

Answer 1

25x^2-16

Answer 2

x^2 is a square

2^2 is a square

so the difference of the squares is

x^2 - 2^2

Answer 3

(5x+4)(5x-4)

Answer 4

you can write x^2 - 2^2 as x^2 - 4 since 2^2 = 4

Answer 5

(k – 2)2

(k2 + 4)(k2 + 4)

k4 – 2

k4 – 16

These are some random answers

k [raised to the] 4 [th power] is a square
of k squared (K squared*K squared)
16 is the square
of 4 (4 * 4 = 16)

Therefore k4 - 16 is a difference of squares!
