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
