Answer:

a factor of 2 is shown, but 4 was factored out

Step-by-step explanation:

The difference of squares is factored as ...

a² -b² = (a +b)(a -b)

Then the given difference of squares factors as ...

144x² -100 = (12x)² -10² = (12x +10)(12x -10)

Each of these factors has a factor of 2 that can be factored out:

= (2(6x +5))(2(6x -5))

= (2·2)(6x +5)(6x -5)

= 4(6x +5)(6x -5)

The first factor should be 4, not 2.
