SUMMARY

The discussion focuses on rearranging the equation y = x² to make x the subject. The correct transformation is x = √y, acknowledging that the solution can yield both positive and negative roots. However, in contexts such as finding the inverse of a function, only the positive root is considered, resulting in x = √y. This clarification is essential for accurately interpreting the equation based on its application.

How do i rearrange this equation to make x the subject?

y=xsquared
 
Mathematics news on Phys.org
y=x^2
x=\sqrt y ?
 
abs(x)=y
+or- sqrt y=x
 
lol :) :) :)
 
Depends on the context. If it is to find the inverse of a function, then it is just SQRT(y)=x - ignoring the negative part...
