Answer:
A.
Step-by-step explanation:
Factoring is the process of taking common terms out of an expression such that one can represent the expression as the result of smaller values. When given the following expression:

First, represent the linear term as the sum of two terms such that each term shares a common factor with the other terms in the expression.

Now take out the common factors,

Thus, the correct option is choice (A).

Where is your question in order to answer it
Answer:
31.77% probability the surgery is successful for exactly five patients.
Step-by-step explanation:
For each patient, there are only two possible outcomes. Either the surgery is successful, or it is not. The probability of the surgery being successful for a patient is independent of other patients. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
A surgical technique is performed on seven patients.
This means that 
You are told there is a 70% chance of success.
This means that 
Find the probability the surgery is successful for exactly five patients.
This is P(X = 5).
