# Math Help - Quadratic equation with floor function.

1. ## 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 $\lfloor 2.3 \rfloor = 2$

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.
