## Coefficients evaluated/shown in an equation

Hi,

I am looking for a solution to my question, "can the coefficients be evaluated/shown as numbers in an equation?"

example)

a:= 3     b:=3   c:=7

2a (x^2) + 3b (x) - (a+b+c) = 0

can the obove be shown as:  6(x^2) + 9x - 13 = 0

only partially as far as I can see

the symbolic will give the answer you are looking for but cannot have the =0

You mean like this:

?

What version of Mathcad or Prime are you using?

Thank you!  It was perfectly working for my purpose!

Actually, my equation is a bit more complex.

When I tried to solve the original without using EQ(), my MathCad 14 just returned the red-colored original.

You can also do it the other way around: First solve symbolically, then plug in the numbers. Like this:

Success!
