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
