here is the question...but the quadratic is just part of it. When an elastic spring is stretced beyond its natural unstretched length, a tension exists in the spring creating simple harmonic motion. The magnitude of the tension is given by the experimental law credited to Robert Hooke...

Hey guys, I've tried to do this quadratic question using the formula but can't seem to get it and don't know if its right or not. x= -b+-√b^2 – 4ac / 2a a= 37.5 b= L c= L^2 Need to find X the sub X into find L in metres. Thanks in Advance
