Hello from MrBillDoesMath
Answer:
See below
Discussion:
Note the Question incorrectly shows (2n^2 +1) ^ 2. It should be (2n + 1) ^2.
So
(2 n + 1) ^2 - (2n +1) =
4n^2 + 4n + 1 - 2n - 1 = ( -1 + 1 = 0)
4n^2 + 4n -2n + (1-1) =
4(X) = 2 (2X)
Key point. The end result of the evaluation is a multiple of 2 so the result is an even integer.
Thank you,
Mr. B
Answer:
add 5 + 4, which is 9 and that's 81 dots
Answer:
1. Add 17 to both sides
2. Divide both sides by 4
Step-by-step explanation:
We have been given the equation
In order to solve the equation, we apply the below mentioned steps:-
Step 1:
Since, 17 is in subtraction with 4x hence, to get rid of this we add 17 to both sides of the equation.
Step 2:
Now, 4 is in multiplication with x, hence to get rid of 4, we do the reverse operation of multiplication which is division.
Hence, divide both sides by 4
Hence, the correct option should be
1. Add 17 to both sides
2. Divide both sides by 4
