How to Rewrite Rational Expressions- This is a pretty complicated equation to solve, given that there are several expressions that are different from each other. It is even more difficult if you can't recognize the common factors. For example: (6x2 + 18x + 15) / x + 3 One of the tricks is to rewrite the expression by seeing the expression as a division between a numerator and denominator. While solving this equation, it is recommended that you remember that the denominator cannot be zero. This equation can easily be solved using the long division method. Why? Let's look at an example: 529/23 Now, if we consider the above equation as a division between the two, we can understand that: 529/23 = 23/1 = 23 Using the process of long division, we can easily rewrite the equation mentioned above. (6x2 + 18x + 15) / x + 3 Rewritten from: (x + 15) / 1. Students can use these worksheets and lesson to understand how rewrite fraction in which the numerator and/or the denominator are polynomials.
