3x^2
Answer:

Explanation:
While solving literal equations could be quite overwelhming, simply solve it by using normal equation solving methods.
For example, if you were to solve 2x + 3 = 9
You would add 3 on both sides and divide both sides by 2 to determine x.
Do the same thing for literal equations, and if in doubts, plug in numbers to check your work.
Step-by-step explanation:
For this problem, add c on both sides, we do this because we are aiming to eliminate the c from both sides.
a+c =2b
In order to find the value of b, divide both sides by 2, we do this because we want to get rid of the coefficient.
This should leave you with the answer of b=a/2 + c/2
Answer:
* = b²
Step-by-step explanation:
You know that the square of a binomial is of the form ...
(x + y)² = x² + 2xy + y²
Matching given terms, we have ...
49 = y²
2xy = 14b
Solving the first of these relations for y, we have
y = √49 = 7
Putting that in the second relation and solving for x, we find ...
2x·7 = 14b
14x = 14b
x = b
Then the first term of the expansion, x², will be b².
The missing term is b².
