What is the solution of square root -4x =100 a. x= -2500 b. x = -50 c. x = -2.5 d. no solution

To solve this problem you must apply the proccedure shown below:

 1. You have the following expression given in the problem above:

 √(-4x) =100 

 2. Then, you have to clear the variable x, as below:

 √(-4x) =100 
 (√(-4x))^2 =(100)^2
 -4x=10000
 x=10000/-4

 3. Then, the result is:

 x=-2500

 4. Therefore, as you can see, the correct answer is first option (option a), which is:

 a. x=-2500
