Answer:
4x^3 + 8x^2 - 23x + 3
Explanation:
Use the distributive property to distribute the first equation into the second.
By doing this you will have two lines that are as follows:
4x^3 + 14x^2 - 2x
-6x^2 - 21x + 3
Adding these equations together would give you the simplified expression:
4x^3 + 8x^2 - 23x + 3
