Factoring polynomial returns numeric value
I'm in the process of refamiliarizing myself with my HP Prime. I've had one for a couple of years but stopped using it because it was too difficult to see. I just bought a new one with the high contrast keys (and it's great ... thanks HP!)
I'm going over some of Eddie Shore's examples and am having some problems. I'm sure the answer I need is simple but I can't figure it out. Eddie's blog ... https://edspi31415.blogspot.com/2016/05/...mands.html I am attempting this example: factor(x^2 + 6*x + 5) returns (x + 1)*(x + 5) What I'm getting is 10.44 rather than (x + 1)*(x + 5). I know what's going on. My 'x' variable is set to 0.8 from some previous examples I did so it seems that the Prime is evaluating (x^2 + 6*x + 5) for 'x' rather than factoring it. What do I have to do to get a return of (x + 1)*(x + 5)? Thanks, Jim
