\(3 × 32 , 85 + 32 , 85 × a × ( a × 1 − a : 1 ) + 32 , 85 × 8 − 32 , 85 × 10\)

\(= 3 × 32 , 85 + 32 , 85 × a × ( a − a ) + 32 , 85 × 8 − 32 , 85 × 10\)

\(= 3 × 32 , 85 + 32 , 85 × a × 0 + 32 , 85 × 8 − 32 , 85 × 10\)

\(= 32 , 85 × ( 3 + a × 0 + 8 − 10 )\)

\(= 32 , 85 × ( 3 + 0 + 8 − 10 )\)

\(= 32 , 85 × 1=32,85\)
