This week in PreCalc 11 we learned about multiplying Rational Expressions and Equations. When multiplying Rational Expressions and Equations, the same rules when multiplying fractions apply. You can multiply across but there are ways to get answers quicker. A  lot of the time when there are rational expressions and equations, they can be factored/simplified more to make it easier for you to solve. My mistake this week was not simplifying as far as I could.

For example: in this question, you have to factor everything, then cross out the like terms. When I did it I did not cross out the like terms but just tried to multiply everything across, which didn’t work. I then was shown that when finding the like terms I can just cross them out which simplifies the equation so much more. Then it was just placing the left over terms together/ over each other/in fraction form and doing simple reducing and division. Then I got the right answer.
