Asked by Andrew
Hi, im having problems with the following problem. The main issue is actually starting the problem.
Find the two points on the curve y = x^4 - 2x^2 - x that have a common tangent line.
First, find the derivative of y(x) so that you know the slope of the tangent line at any given x.
The derivative will be a quadratic formula for which there may be two solutions.
