<p>Whenever I try to expand or factor an expression, it returns a decimal value. I enter in the parentheses and everything correctly...what am I doing wrong?</p>
<p>two guesses
first, you have a constant stored to the variables (eg, 5 is stored to x, so expand((x+3)^2) will return 64
or
you’re in approximate mode, not exact mode.</p>
<p>Well, I have it in auto mode, which returns an exact value if possible, and if not, it returns an approximate value.</p>
<p>It’s just that I shouldn’t be receiving a value when I use the factor or expand features.</p>
<p>Like if I put in EXPAND((x-5)^3) and hit ENTER, it gives me -2.83567 when it should be giving me x^3 - 15x^2 + 75x - 125.</p>
<p>use the command “delvar x”</p>
<p>
</p>
<p>That fixed it. Thanks!</p>
