In Reply to: Finding prime factors of binomial and trinomial? posted by Mitch on September 24, 2002 at 22:09:56:
An integer greater than one is called a prime number if its only positive divisors (factors) are one and itself. For example, the prime divisors of 10 are 2 and 5; and the first six primes are 2, 3, 5, 7, 11 and 13. A prime number is any number with no divisors other than itself and 1, such as 2 and 11. Any number can be written as a product of prime numbers in a unique way (except for the order).
so for equation 1
prime factors of 16 are 2(4) of 40 are (2(3))5 0f 25 is 5(2)

try there until you really get it.
: I'm struggling with learning how to do these types of problems, can any one show me how to work these two problems step by step?
: 1) find prime factors of the trinomial
: 16x^2-40xy+25y^2
: 2) find prime factors of the binomial
: 12x^2y^2-27
: Thanks, very fustrated,
