How do you factor 5x2 - 45?
To factor any term, divide by the LCF (largest common factor) of the term. For 5x2-45, the LCF is 5. 5x2-45 = 5(x2-9) It can, of course, be factored even further to become: 5(x2-9) = 45(x2/9 - 1) but when factoring, we usually don't need to go past 5(x2-9) (for example, you've figured out that x2 = 9, thus x = +/- 3.)
GCF of 15 and 45?
It's 15. 15 can divide evenly into 45.
What 3x what equals 45?
If: 3x = 45 Then: x = 15
Write 6 out of 45 in simplest form?
6/45 =2/15 because 3 goes into 6 two times and into 45 15 times.
Is 8 over 15 greater than 20 over 45?
Yes, because 8/15 = 24/45

LCF OF 15 and 16?
Since the CFs of neither match, you have to multiply the two numbers together. The answer you get is the LCF. You do the math.
What is the answer to 8 over 15 plus 2 over 9?
The LCF is 45 because 15 x 3 equals 45 and 9 x 5 equals 45. Now, multiply 8 x 3 to get 24 and 2 x 5 equals 10. 24 plus 10 equals 34. The answer is 34 over 45.
