How to Rewrite Expressions To Make Them Equivalent -
Algebra has been haunting students since grade 4th. It strikes fear in the hearts of many because of the fact of being complicated. In retrospect, you are sometimes faced with expressions that are not equivalent, and in order to solve them, you need to make them equivalent, which can be done with a few properties only.
Take a look at the following properties to rewrite the expressions to make them equivalent.
**Distributive Property** - Consider this example;
2x(3y + 2) - Start with 2x being multiplied with each and every element of the bracket. It will make it easier to walk through the process. Distributing 2x throughout the equation means multiplying 2x with 3y as well as with 2. The answer you will get after multiplying is 6xy + 4x.
Now the expression you've got is the equivalent expression
**Using Factoring** - Break down the equation in parts in order to find the equivalent expression. Separate the common factors. For example, it is the same expression; 6xy + 4x. In this expression, you need to identify the common factors an take them out, which in this case, is 2 for both elements.
2(3xy + 2x)
Now you can see another common factor, x. 2x(3y + 2). This gives you the equivalent expression, and you can write 6xy + 4x = 2x(3y + 2). These worksheets and lessons will help students learn to rewrite expressions and make them equal to one another.
