This is I'm sure a blindingly easy Maxima question that I've hunted for an answer for a while now but can't seem to fish it out...

I have a quadratic that I've solved for x. The solve function gives its output in the form of x= 0.6492374 and x= -0.3473. I need to do something with those numbers afterwards which means I need them to just be numbers rather than x= a number.

I'm sure there has to be a straightforward function for this I just can't seem to find it.

Thanks.
