Good morning! 
This week we are going to solve all types of EQUATIONS. Your task is here, you have all week to do it:

Good morning 4º ESO A!
Here you have a different way to solve RATIONAL EQUATIONS, just in case you find difficulties by solving them like we use to:
             Example:

While I was checking your homework, I realised that yo have to practise a little bit more with the RATIONAL EQUATIONS
The problem is that most of yo are having difficulties finding out the common denominador in each equation.
So, I recommend you to do the following exercises of your text-book and, after that revise your solutions:





Here you have the solutions of your text-book´s exercises

STEPS TO SOLVE A RATIONAL EQUATION

Let´s solve the last equations of your homework
            Equation:

          Equation:

EQUATIONS
Rationals Equations
To solve these equations yo have to do correctly the following operations with polynomials and algebraic fractions:

 If you want to practise with polynomials and algebraic fractions,  here you have this link
                                                      http://www.minimath.net/index_es.htm

You can try to do on your note.ook these exercises and check your results with this instrument (not nneded to say that the more you prctise the more you learn)
Exercise 1
Simplify
Exercise 2
Operate, previously reducing to common denominators (help) and after that simplify the results
                   
Exercise 3
Operate and simplify
              
Exercise 4
Multiply or divide these fractions but, first of all decompon each polynomial in prime factors:

 We´re going to revise how to find out polynomials´Least Common Factor (or LCD or GCM = Great Common Multiple) in order to add/substract algebraic fractions with unlike denominators:
                                                Great C. Factor o Denominator














                                           


                           
 Adding/substracting fractions
