In my math class my teacher told me there was only one way to do this problem and that was through factoring and it was really long
but i said what if you took the cubic root of both sides you would get 8xsquared -3=0 wich eventually carried out to 1.2247 is this not a lidget way to do this problem? she would not listen to me she said the only way to do this problem is through factoring. am i right or is she right

If x is inversely related to y, then that means that if x increases, y decreases? It means that x=z*1/y, right? Or is it more accurate to say that that's a negative relationship?

I'm trying to tell whether mass is inversely related to acceleration in the formula a=f/m
