Factoring polynomial returns numeric value

[Skyblues]

I'm in the process of re-familiarizing 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
