Hi, I am having trouble with this problem. Directions are: Find an equation for the tangent line to y=f(x) at the specified point.

f(x)= e^2x / x^2 ; Where x= 1

I used the quotient rule and obtained: ((x^2)(2e^2x) - (e^2x)(2x)) / x^4

I hope I am correct up to here, I don't know what to do from here to get the equation for the tangent line, the book has the answer as: y=e^2 If someone could illustrate how this is obtained, Thank You.
