Is this correct?
(bcos30-85.7)(bcos30-85.7)=b²cos²30-85.7cos30-85.7bcos30+85.7²
(bcos30-85.7)(bcos30-85.7)=b²cos²30-85.7cos30-85.7bcos30+85.7²

SUMMARY
The discussion focuses on the simplification of the trigonometric binomial expression (bcos30 - 85.7)(bcos30 - 85.7). The correct expansion is identified as b²cos²30 - 2b(85.7cos30) + 85.7². A crucial point made is the necessity of including the b term for the 85.7cos30 component during simplification, which is essential for accurate results.
