One of the factors of 3p5 - 12p3 is:. p4. p + 2. p2 + 4. 4

To answer the question above, identify first the greatest common factor for the numerical coefficients. That is 3. Next, determine the GCF for the variables p^5 and p³. Thus, factoring the given leads to,

3p³ x (p² - 4)

The second factor is a difference of two squares. Further simplification of the expression leads to,

3p³ x (p + 2) x (p - 2)

Thus, the answer is p + 2.
