Answer:

Step-by-step explanation:

First, we can factor out a common factor of 4x³ from the first two terms: 4x⁴ + a = 4x³(x + a/4x³)

Next, we can factor out a common factor of x + a/4x³ from both terms: 4x³(x + a/4x³) = x(x + a/4x³) * 4x²

Finally, we can factor out a common factor of x + a/4x³ from both terms: x(x + a/4x³) * 4x² = x(4x²) + x(a/4x³) = 4x³x + ax/4x³

So the factored form of 4x⁴+a is 4x³x + ax/4x³

Note that this is assuming a is a constant.
