The decimal search method is an inexact way of finding a solution of an equation by calculating values and plotting graphs.

Basically just come up with any input numbers, find the output numbers, plot the graph as best as you can and try to estimate where the graph crosses the x-axis. Try to zoom in, calculate closer numbers, plot a section of the graph closer to what you need, estimate again, and repeat. You can do this as long as you need to to get the desired accuracy of your result.

Note: this method takes a while, and so should be avoided if possible.
