Answer:

  • as written: 2(x² +1) = 2·3·67
  • as standard-form quadratic: 2(x² -200) = 0

Explanation:

A prime factorization of a polynomial is one in which each factor cannot be factored further using integers. Here, we can remove a factor of 2 from each side to get ...

2(x² +1) = 2(201)

The constant 201 can be further factored to primes:

2(x² +1) = (2)(3)(67)

__

If the equation is written in standard form:

2x² -400 = 0

again, a factor of 2 can be removed:

2(x² -200) = 0

If the binomial constant were a perfect square, this could be factored further. It is not, so it can't.
