10y² - 4x²  =  2(5y² - 2x²)
16y² - x²  = (4y + x)(4y - x) ................this is a difference of squares!
8x² - 40x + 256 = 8(x² - 5x + 32)
4x² - 48x + 9  

Answer:

B.  [tex](4y)^2-x^2[/tex]

Step-by-step explanation:

We are asked to choose the correct option that shows the difference of squares.

We know that difference of squares is in form [tex]a^2-b^2[/tex].

Upon looking at our given choice, we can see that option B is the correct choice as:

[tex]16y^2-x^2=4^2\cdot y^2-x^2=(4y)^2-x^2[/tex]

Therefore, option B is the correct choice.
