Sorry it is important for me to constrain the value of 'a' between
c(0,1)

Hi there,

I would like to solve a simple equation in R

a^2 - a = 8.313

There is no real solution to this problem but I would like to get an
approximate numerical solution. Can someone suggest how I can set

this up?

Thanks in advance,
Diviya

What is your definition of approximate?  For all values of a in the interval [0,1], a^2-a is less than or equal to 0.  Or am I missing something?
