Answer: The equivalent factored form of x²-16 is (x+4)(x-4).
Step-by-step explanation:
Since we have given that
[tex]x^2-16[/tex]
We need to find the number of zeros.
Since it is quadratic equation , so, it has 2 zeroes
Therefore, number of zeroes = 2
Now, we need to factorize the above quadratic equation.
[tex]x^2-16\\\\=(x)^2-4^2\\\\\text{ Now, we will use identity :}"a^2-b^2=(a-b)(a+b)"\\\\=(x-4)(x+4)[/tex]
Hence, the equivalent factored form of x²-16 is (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)
