    Quadratic equation with floor function.

    Calculate Real values of x that satisfy the equation 6x^2+77\lfloor x \rfloor +147 = 0

    Where \lfloor x \rfloor = floor function.

    like \lfloor 2.3 \rfloor = 2

    Hello jacks

    I have already shown you how to solve one of these in a previous post.

    Solve the quadratic ignoring the floor.

    Then guess an integer value for \lfloor x \rfloor close to the solution, and check if the value of x is consistent with that guess.

    Please try to work out a bit more of this problem.
