Answer:
-1/2 or x=2
Step-by-step explanation: The first step you need to do in getting your answer is factoring ,you will factor the left side of the equation first:
(2x+1)(x-2)=0
Next, you will set the factors to equal to "0":
2x+1=0 x-2=0
Then you'll proceed to solve the problem using the basic algebraic equation problem solving steps .When you do this you'll be left with answers of x=-1/2 and x=2
Given:

To find:
The missing value.
Solution:
Let x be the missing value.
We have,


Subtract
from both sides.




Multiplying both sides by 5, we get

So, the missing value is 3.
Therefore, the correct option is C.
Answer:
A) 25
