OpenStudy (anonymous):

the ehow method...

OpenStudy (anonymous):

since the question is find all square roots, there may be imaginary ones. when i learn this in pre-calc there is a specific formula for this. i just forgot so i refer him to the ehow :)

OpenStudy (anonymous):

the square roots of a number are solutions to: \[x^2 = n \iff x^2-n = 0\] which by the fundamental theorem of algebra will have 2 solutions.

If u write sqrt(2500) it's 50, else it's 50 and -50.
