Since we want it in the form: (x - a)², let's first expand (x - a)² and then equate for the coefficients.
(x - a)² = x² - 2ax + a²
x² + 4x - 15 = x² - 2ax + a²
Now, let's focus on the middle term.
4x = -2ax
4 = -2a
a = -2
Thus, we know that a = -2
Then, we can say (x + 2)² = x² + 4x - 15
x² + 4x + 4 = x² + 4x - 15
Thus, 19 units are needed in order to complete the square to produce:
(x + 2)²
Let one of the number be x
The other number will be x + 2
x + x + 2 = 15044
2x + 2 = 15044
2x = 15044 -2
2x = 15042
x = 7521
x + 2 = 7521 + 2 = 7523
The office number is 7521 and 7523

Step-by-step explanation:
Mean basically just means average. To find the mean, add the numbers together and divide them by the number of numbers.
17 + 20 + 17 + 33 + 22 + 23 = 132
After that, divide by 6 since there are 6 numbers
132 ÷ 6 = 22

Have a good day :)
