Documenting the Expansion of Radical Binomials

As part of your training documentation for the engineering department, you need to write a brief guide on expanding binomials with radical terms, such as those used in tolerance calculations. Recalling the standard expansion method, describe the step-by-step process for simplifying the expression (3−27)(4−27){}(3 - 2\sqrt{7})(4 - 2\sqrt{7}). In your response, clearly list the four initial terms generated during the expansion and state which terms are combined to produce the final simplified result.
