there is exactly one line that is tangent to two different points on the graph of y = x^4 - 2x^2 - x. Determine the coordinates of these two points. Please help me to solve this problem.

When we compute the derivative it will give us a general slope function. The slope of the tangent line at these two points will be the same, but we will need a different value of x... I'm not sure but maybe we can write:|dw:1351470613204:dw|
