How to write Quadratic equation with negative coefficient
How to write Quadratic equation with negative coefficient in fp
For a=1, b=-5, c= 6, $ca x^2+cb x + cc=0$ gives 1x^2 + -5x + 6
But i want to have x^2 -5x + 6

Will also work with addterm -5x
in addition to the intended addtermcb x
.
The addterm
macro takes a single argument, expands it once, and passes it to addtermaux
. The addtermaux
definition will grab the first token of the argument and examine to see if it is a minus -
character. If so, it typesets a -
and the rest of the argument. If not, it sees whether the first token was a +
character. If so, it typesets a +
and the rest of the argument. If neither of the above cases apply, it typesets a +
and the complete argument.
In this way, the right output is provided whether cc
is set to 6
or set to +6
.
