Multiplying Out Brackets is the process of expanding an equation or expression that has terms within a set of brackets. By multiplying each term within the brackets by its corresponding term outside the brackets, it is possible to eliminate the use of brackets and produce a linear equation or expression instead.

Multiplying out brackets can help to simplify equations by removing the need for parentheses or other grouping devices. It also helps to reduce complexity and can make equations easier to understand. Additionally, it can help when solving equations as it reduces the amount of steps needed in order to arrive at a solution.

To multiply out brackets, you must take each term inside the bracket one by one and multiply it by its corresponding term outside the bracket. Each result should then be added together in order to get your final answer without any brackets present.

There are certain cases where you should not perform multiplication out of brackets, such as when dealing with complex numbers or imaginary numbers. In these cases, it is usually best to leave the terms inside a set of parentheses unchanged as multiplying them could result in an inaccurate answer being produced.

Another way for eliminating parentheses is factoring, which involves breaking down an equation into two factors that multiply together to form a given expression without using parentheses. This technique is used mainly when dealing with more complicated equations that contain multiple variables and involve advanced mathematical operations such as exponents and fractions.
