X² + 10x +2 = 0 .Complete the square of (x² + 10x + ??)
We know that (10x) is equal to twice the square root of the 1st (x) by ??
10x = 2.x.(??) and ?? = 5 and its square is 25. Then I have to add 25 and subtract 25 so that not to change the equation:
(x² + 10x + 25) -25 +2 =0
(x+5)² -23

Answer:
The total change in the amount of money in my account is $ 9.60
Step-by-step explanation:
Given:
Amount of money deposited each week, 
Amount of money withdrawn each week, 
∴ Amount of money deposited in 4 weeks, 
∴ Amount of money withdrawn in 2 weeks, 
Now, amount of money left in the account is the difference of the two amounts.
So, amount left = 
Therefore, the total change in the amount of money in my account is given as:
Total change = Initial amount after 4 weeks - Final amount in the account.
Total change = $ 50 - $40.4 = $ 9.6
