I think this is what you mean.
First step, get rid of any x expressions in the denominators by multiplying both sides by x^3.
Distributive property
Dividing same base, subtract exponents
Simplify.
A quadratic equation.
Divide both sides by 4.
Factor the quadratic equation.
Take the square root of both sides.
Check your answer using the value for x and your original equation.
Now plug those values into your original equation.
Good answer.
