Box function . Solve for x [x]^2 - [x] - 3 = 0Box function [x] = greatest integer less than or equal to x.

we realize that in the event that we are a container work ⌊x⌋ we will discover an answer of it which is equivalent or short of what it. For instance ⌊8.3⌋=8,⌊-1.8⌋=-2. Here we utilize the quadratic recipe to understand for x. x=(- b±√(b^2-4ac))/2a, putting the qualities b = - 1, c= - 3, a = 1. We get the estimation of x to be 2.30 and - 1.30. Utilizing the container work we have ⌊x⌋=⌊2.30⌋=2,⌊x⌋= ⌊-1.30⌋= - 2.
