Answer:
(x + 4)(x - 4)
Step-by-step explanation:
Hello!
Use the difference of squares method: (a+b)(a-b) = a² - b²
Since x² and 16 are perfect squares and they're being subtracted, use the format of the formula.
x is being squared to make x².
4 is being squared to make 16.
Take the values and substitute them directly.
(x + 4)(x - 4)
