There are many ways, but here is one.
Example:
A. x2 + 5x + 6
coefficients: 1, 5, 6
You have to find two numbers that the two ends multiply to get the sum of the middle coefficient in the order of ax2 + bx + c (read on to understand)
1 x 6 = 6
Find two numbers that multiply to 6, but add to 5
1 6 : 1 x 6 = 6, 1 + 6 = 7 X
2 3 : 2 x 3 = 6, 2 + 3 = 5 <---
So, the special numbers are 2 and 3.
Now, add them into this: (x+_)(x+_)
Both are positive, so it works! (x+2)(x+3)
Let's check.
(x+2)(x+3)
Use FOIL Method (first, outer, inner, last)
= x2 + 2x + 3x + 6
= x2 + 5x + 6
It works! Now, if you have trouble understanding, reread it a few times, and you'll get it in a blink!
Divide the factor into the number. If the answer is a whole number, the factor is a factor.
1 is a factor of every number.1 is a factor of every number.
A composite factor is a factor that is a composite number, as opposed to a prime factor which is a factor that is a prime number.
The greatest factor of any number is the number itself. The second greatest factor of any even number is half the number. The second greatest factor of any composite number is the number divided by its smallest prime factor. The second greatest factor of any prime number is 1.
If one number is a factor of another number, the greatest common factor will be the lesser number. Example: 3 and 9 3 is a factor of 9 3 is a factor of 3 There can be no higher factor of a number than the number itself. Therefore, the GCF of 3 and 9 is 3.
Every number has a factor.
A factor can or cannot be a prime number Ex: 2 is the factor of all other even numbers its a prime number but 9 is a factor of 18 and its not a prime number A prime is a factor but a factor being a prime number varies
No, that's just a factor. A common factor is when that factor is also a factor of another number.
The greatest factor of a number is the number itself.
One is a factor of every number.
Divide the smaller number into the larger number. If the answer is not an integer, the smaller number is not a factor.
The greatest factor of any positive number is the number itself.
