Simplify the numerator. You should get just 13. Show your work. f'(x) = 3(5x + 1) + 5(3x  2) over (5x + 1)^2

Best ResponseYou've already chosen the best response.1Use the distributive property on: 3(5x + 1) + 5(3x  2) Which is your numerator. a(c + d) = ac + ad You will get 2 terms that will cancel and 2 other terms that can be combined.

Best ResponseYou've already chosen the best response.1That is now for you to show it. You should show your work now instead of me because that is sufficient help for you to at least start to try to solve it. Go ahead now. It's your problem so take ownership and do some work.

Best ResponseYou've already chosen the best response.1You did well on the first half, but: 5(3x  2) is not equal to 5x + 10 the "10" is right but concentrate on the "5x". That is where you went wrong a little bit.

Best ResponseYou've already chosen the best response.1You have 5 times 3x There is a negative sign involved. Always check your signs.

Best ResponseYou've already chosen the best response.1Yes. So, your numerator is : 15x + 3 + 15x + 10 so far. So now, 2 of the terms will cancel and the other 2 can be combined.

Best ResponseYou've already chosen the best response.0ok so 15x and 15x will cancel and we will combine 10 and 3 to get 13 :)
