Prime factors are factors of a composite number that are indivisible except by the number 1 or the number itself. The answers to your questions are the following:

1. Yes, it is possible especially for very large numbers.
2&3. No, because as mentioned previously, the default prime factors of numbers are 1 and the number itself. For example, 2 is a prime number. Its factors are 1 and 2.
4. Prime factorization are useful in fields of encryption. They make use of the basic prime numbers for the arithmetic modulus with the general equation: n=pq.

Which expression is a difference of squares with a factor of 5x − 8?

Olegator [25]

Answer:

$25x^2-64$

Step-by-step explanation:

Remember that the formula for the difference of squares is $a^2-b^2=(a+b)(a-b)$ . The formula implies that if (5x - 8) is a factor, then (5x + 8) is the other factor. We can use our formula to find which one is our difference of squares:

$(5x-8)(5x+8)=(5x)^2-8^2$

$(5x-8)(5x+8)=5^2x^2-64$

$(5x-8)(5x+8)=25x^2-64$

We can conclude that the correct answer is $25x^2-64$ .
