Answer:
1. 12/26, or simplified as 6/13, or about 46%.
2. 5/26, or about 19%.
The factors would be (x-9)(x+4).
You can use the decomposition method to find this. I personally use the chart method so I do not necessarily know how to explain the decomp method in detail. However the idea and end goal are the same for both of them.
Try to find what multiplys to the last part of the polynomial but will add to the middle part.
To check your work/factors you can try multiplying/foiling them out again to see if you get your original polynomial.
Answer:
Here we will explain how to calculate one half of 80.
One half of 80 is simply one half times 80, which can be written as follows:
One/half x 80
Furthermore, you can convert "one" to "1" and "half" to "2" and then the equation and answer is:
1/2 x 80 = 40.00

Answer:
The second one, my order is different, but they are equivalent answers
Step-by-step explanation: 6 22 22 18
(√6 + √11) / (√5 +√3) multiple top and by (√5 - √3) note the minus
(√6 + √11) × (√5 - √3) / (√5 +√3) x (√5 - √3)
(√30 + √55 - √18 - √33) / (5 - 3)
(√30 + √55 - 3√2 - √33) / 2
