Answer:
5w³(5w³ + 7)
Explanation:
For this question, you basically have to do the reverse of distributive property, and divide the GCF's out.
So the coefficients of 25w⁶ + 35w³ both have a common factor of 5.
This would yield us: 5(5w⁶+ 7w³)
After that we can also factor out w³.
Therefore,
5w³(5w³ + 7).
To check this answer you just have to apply distributive property to see if it gives the same result as the question.
Hope this helps!
