4/9 2/5 5/7 is sorted from least to greatest
This can be rewritten as
(x -6)² = 90 . . . . . the left side is already a perfect square
x -6 = ±√90 . . . . . take the square root
x = 6 ±3√10 . . . . add 6
For finding GCF, just find the least number among them.
For example:
a.) 6x^2 - 9 find what number that can be divided to 6. In this case, it is 2 and 3.
You can't divide 9 by 2 so the answer in this equation would be 3.
b.) 2a^ 2 + 22a + 60 I's just the same method to use. In this case, we will use 2a^2. The factors that can be divided to 2 is (2,1). So we will choose 2 because it is the GCF of 2 and the equation is divisible by 2.
Answer: 
Step-by-step explanation:
1. You have the following information given in the problem above:

2. To solve this exercise, first you must multiply the number that ar inside the parentheses and then you must add all of them, as you can see below:

3. Rewriting is as a decimal, you have that the answer is:
