Answer: Yes, Cecile factored the polynomial correctly.

Step-by-step explanation:

She did factored the polynomial correctly, let's prove it:

The initial polinomial is 16x^6 - 9

and she has:

(4x^3 + 3)*(4x^3 - 3)

lets dstribute this:

4x^3*4x^3 + 4x^3*(-3) + 4x^3*(3) + 3*(-3)

16*x^(3 + 3) - 12x^3 + 12x^3 - 9

16x^6 - 9

So Cecile is correct.
