Consider the curve defined by 2y^3+6x^2y-12x^2+6y=1

I found dy/dx= 4x-2xy/x^2+y^2+1

Now it wants me to write an equation of each horizontal tangent line to the curve.

The line passes through the origin with slope -1 is tangent to the curve at point P. Find the x-and y-coordinates of point P.

I dont understand how you do this.

if:


A= 20 -10
......12 19


B= 15 14
......-10 6


C= -5 7

Find each sum, difference, or product. If the Sum does not exist, write "impossible"

The it says to do the following problems with the Matrices:

1. A + C

2. B - A

3. 2A

4. -4C
