Can someone show me how to find the points that intersect with the graph of the function f(x) = 1-x^2 and the tangent line that goes through the point (2,0).

The point is on the curve . Say the point is . The slope of the tangent line is . So the tangent line is
The line passes through the point , then
Therefore,
