What is obtained after simplifying (5(2p-3q)-3(p+4q)+2q)?

Answer and explanation

Correct answer: 7p-25q

Expand the brackets: 5(2p-3q)=10p-15q and -3(p+4q)=-3p-12q. Thus, the expression becomes 10p-15q-3p-12q+2q. Combining like terms gives (10p-3p)+(−15q−12q+2q)=7p−25q. Therefore, option A is correct. Remember that the minus sign before 3(p+4q) affects both terms inside the bracket.
