Best ResponseYou've already chosen the best response.0there is a standard technique for taking the derivatives of a polynomial. first find the terms with similar degrees of x and combine them.

Best ResponseYou've already chosen the best response.1If you're deriving a single one of those terms, the move is this: \[ax^b\] The derivative of this is: \[a \cdot b \cdot x^{b  1}\] The exception is for a constant (no power of x), which derives to 0.

Best ResponseYou've already chosen the best response.1In this case, you can do that for each one and you get: \[3 \cdot 2x + 15 \cdot 1 = 6x + 15\]
