Simplify six multiplied by three 𝑏 plus two plus four multiplied by two 𝑏 plus four.
Our first step is to expand or multiply out the parentheses or brackets. Six multiplied by three 𝑏 is 18𝑏 and six multiplied by two is equal to 12. Likewise, expanding the second bracket four multiplied by two 𝑏 is eight 𝑏 and four multiplied by four is equal to 16.
At this stage, we need to group or collect the like terms. 18𝑏 plus eight 𝑏 is equal to 26𝑏. Likewise, 12 plus 16 is equal to 28. This means that our simplified expression is 26𝑏 plus 28.
