Calculate First Polynomial: Calculate the first polynomial: 2+5+(−6)×3+(−12)+8÷(−2).- Perform the operations in the correct order (PEMDAS/BODMAS rules).- Multiplication and division first: (−6)×3=−18, 8÷(−2)=−4.- Then addition and subtraction: 2+5−18−12−4=−27.
Calculate Second Polynomial: Calculate the second polynomial: [2+5+(−6)]×3+(−12)+8÷(−2).- First solve inside the brackets: 2+5−6=1.- Then multiply by 3: 1×3=3.- Perform remaining operations: 3−12+(−4)=−13.
