Find the equation of the tangent line?
Find the equation of the line tangent to the graph of y=5x(x²-4x+5)^4 at the point (2,10).
I got that y'=5(x²-4x+5)³(8x²-16x). I don't know if that is right. Once I get the derivative figured out do I just put 2 in for x and solve?

Re: Find the equation of the tangent line?
Hi taylor;
Check your work on how you got the derivative.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
