Answer:

C. 3x⁵ + 14x³- 7x²

Step-by-step explanation:

Given the expression:


\mleft(3x^5+8x^3\mright)-(7x^2-6x^3)

First, remove all brackets:


=3x^5+8x^3-7x^2+6x^3

Next, collect and combine like terms:


\begin{gathered} =3x^5+8x^3+6x^3-7x^2 \\ =3x^5+14x^3-7x^2 \end{gathered}

An equivalent expression is 3x⁵ + 14x³- 7x².

The correct choice is C.
