Sorry, can't do what you ask. You asked to 'factor the following equation' but then you didn't provide the equation. You gave a quadratic trinomial. Equations are called equations because they have an equals sign in them. is an equation, but is NOT an equation and neither is .
Be that as it may, the quadratic trinomial can be factored, but the question is: factored over what set of numbers?
You can take a 4 out of each of the terms:
And since which is NOT a perfect square, if you are factoring over the rationals, then you are done.
But if you are factoring over the reals, which you can do because , then
