The common practice is to use "^" (shift-6) when typing an exponent.
I believe your equation is this:
(m^2-1)x^2 - (m+3)x + (4-m^2) =
The equation is quadratic whenever the coefficient of the x^2 term, m^2-1, is non-zero.
m^2-1 is equal to 0 only when x=1 and when x=-1; so the equation is quadratic for all values of x EXCEPT 1 and -1.
ANSWER: all x except 1 and -1
