    1. The problem statement, all variables and given/known data
    show that the tangent line to y=(x2+x-2)3+3 at (1,3) is also tangent to the curve at another point

    2. Relevant equations

    3. The attempt at a solution
    at 1
    dy/dx = 0

    Then solving the equations y=3 and y=y=(x2+x-2)3+3 will give you two solutions, you know (1,3) is a solution, you just need to get the other solution.
