For this case we must find the value of the variable "x" of the following expression:
[tex]\sqrt {-4x} = 100[/tex]
Now, we square both sides of the equation:
[tex]-4x = 100 ^ 2\\-4x = 10000[/tex]
We divide between -4 on both sides of the equation:
[tex]x = \frac {10000} {- 4}\\x = -2500[/tex]
ANswer:
[tex]x = -2500[/tex]
