Step-by-step explanation
The given question can be solved if we simplify the given expression
We are given the expression:
![48a^3-75a](https://img.qammunity.org/2023/formulas/mathematics/college/spdtgq0mlrjrftziusciuaujmszfs8rvur.png)
To find the equivalent expression, we can factorize
![\begin{gathered} =a(48a^2-75) \\ =3a(16a^2-25) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/i2hzjwsdlsitqr0z1l4ydnuc4p20gkmutf.png)
Thus, we have 3a(16a²-25)
We can simplify further by applying the difference of two squares
![3a(4a+5)(4a-5)](https://img.qammunity.org/2023/formulas/mathematics/college/kkbo49p2xho5f4tpurmn4n5lkachpc6nak.png)
Hence, we also have 3a(4a+5)(4a-5)
Also, we can re-write the expression as
![\begin{gathered} -75a-48a^3 \\ =-3a(25-16a^2) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/r4bsx3osv4rhb9rjw8rul29ubft3c0z6rv.png)
Thus, we will have
-3a(25-16a²)
Therefore, we have 3 answers
3a(16a²-25)
3a(4a+5)(4a-5)
-3a(25-16a²)
