Use implicit differentiation to find the slope of the tangent line to the curve at the specified point.
3(x^2 + y^2)^2 = 25(x^2 - y^2) ; (2,1)
This is where I'm stuck:
I know how to get up to the first equation...and I know how to get to the final answer from the second equation, but I have no clue how to get from the first equation in the picture to the second in the picture.It kind of reminds me of this:
Please help me if you could...I tried factoring out the twos, I just can't figure out how to get the same polynomial in the numerator and denominator...i mean, how the heck do the twos disappear? How does the 25 appear in both the numerator and denominator? I don't understand what steps are being taken here.
