I have a very long quadratic equation where each of the variables are multiplied by a mathematic exoression of other variables instead of by constants

Is there a free online tool to simplify it

f(y) * x ^ 2 + g(y) * x + h ( y ) = 0

a = f(y)

b = g(y)

c = h (y)

x equals the opposite of b plus or minus the square root of b squared minus 4 A C divided by 2 a

f(y), g(y) and h(y) are too long to write here

I solved for x as a function of y but I want to shorten it to a simpler form
