For this case we have the following polynomial:

The first thing to do is to place the variables on the same side of the equation.
We have then:

We complete the square by adding the term (b / 2) ^ 2 on both sides of the equation.
We have then:

Rewriting we have:

Therefore, the solutions are:
Answer:
the solution set of the equation is:
The answer is
C' = (0,3)
good luck
Answer: We are given:

We need to find the z scores for the following vacation expense amounts:
$197, $277, $310
We know that z score formula is:

When
, the z score is:



When
, the z score is:



When
, the z score is:



Therefore, the z scores for the vacation expense amounts $197 per day, $277 per day, and $310 per day are -0.83, 0.5 and 1.05 respectively
