I should have mentioned what my current output looks like.  Given this input:

== ASCII MathML ==

Suppose

    $$ ax^2+bx+c=0 $$

and

    $$ a!=0 $$

We first divide by  $$a$$ to get

    $$ x^2+b/ax+c/a=0 $$

Then we complete the square and obtain

    $$ x^2+b/ax+(b/(2a))^2-(b/(2a))^2+c/a=0 $$

The first three terms factor to give

    $$ (x+b/(2a))^2=(b^2)/(4a^2)-c/a $$

Now we take square roots on both sides and get

    $$ x+b/(2a)=+-sqrt((b^2)/(4a^2)-c/a)$$

Finally we move the $$ b/(2a) $$  to the right and simplify to get 
the two solutions:  

    $$ x_(1,2)=(-b+-sqrt(b^2 - 4ac))/(2a) $$

I get this displayed:
