Find the derivative of p(x) with respect to x where p'(x) = (50*x^4)+(60*x^3)+(78*x^2)+6 Your last answer was: p(x) = (5x+3 x-3) (2x+3x+4) 50 x++60 x+78 x+6 Your answer is not correct. Hint: either expand p(x) first and then differentiate (probably the easier alternative, in this case) or use the product rule to differentiate p(x) first and then simplify the result.
