can someone explain to me the steps to solve this problem?
find the derivative: (3x^2+7)(x^22x+3)

I won't solve it but...
Since it's multiplied.
It's the multiplication rule for derivatives.
(derivative of the first equation)(second equation)+ (first equation)(derivative of the second equation) 
3x^46x^3+16x^214x+21
