Answer:
Fourth option: (x-4)(x+4)
Step-by-step explanation:
x^2-16
Using a^2-b^2=(a-b)(a+b) with:
a^2=x^2→sqrt(a^2)=sqrt(x^2)→a=x
b^2=16→sqrt(b^2)=sqrt(16)→b=4
Then:
x^2-16=(x-4)(x+4)
Answer:
The number of zero pairs that will be added to the board is
✔ 4
The equivalent factored form of x2 – 16 is
✔ (x – 4)(x + 4) (D)
