How to approach solving Complicated Mathematical Expressions
An algebraic expression is any mathematical phrase that includes a combination of constants and variables. It cannot be solved; it can only be simplified as it has an "equals" sign. Any complicated mathematical expression can be simplified, no matter how complicated it may be, by learning the basics.
Suppose you get an expression: 3x^{2} + 5 + 4x^{3} - x^{2} + 2x^{3} + 9
The first task is to make sure it is arranged in the right order. Like this: 3x^{2} - x^{2} + 4x^{3} + 2x^{3} + 5 + 9
Now it can be simplified like this: 2x^{2} + 6x^{3} + 14 The equation cannot be solved any further. The second tip for solving a complicated mathematical expression is that you must know how to factor a number.
Suppose you are working with an algebraic expression, which means that there is an equal sign. Then the problem can be solved or simplified further by taking out the terms that are common.
These worksheets and lessons teach students to breakdown expressions into understandable parts and rewrite them.
