Answer:
To solve the expression 6a² + 12ab - 3a(................., we need to determine the missing term in the parenthesis.
Let's break down the given expression step by step:
Explanation:
1. The expression starts with 6a², which means we have a term with the coefficient 6 and the variable a raised to the power of 2.
2. Next, we have 12ab, which means we have a term with the coefficient 12, the variable a, and the variable b.
3. After that, we have -3a(... which means we have a term with the coefficient -3 and the variable a, followed by a parenthesis indicating the missing term.
