Imput A, B, and C, then hit enter. If one of the X's is not a whole number, such as it has a decimal, than click once on the 'refine all button'. After doing so, slowly refine '-B' and 'sqrt #' until you have the lowest whole numbers. Than just draw the whole equation with the numbers onto the paper. Warning: sometimes the calculator is wrong. Make sure the answer matches up.
