Question 1130126
.
<pre>
    If you have difficulties factoring such a quadratic polynomial  
        (in other words, if you do not see the factoring formula immediately before your eyes in your mind)
     then do the following 

        - find the roots of the given quadratic polynomial using the quadratic formula;

        - then factor the given quadratic polynomial using its roots.
</pre>


This method works ALWAYS like an army tank.



It means that &nbsp;<U>if the factoring formula does exist over rational (or integer) numbers</U>, 


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>then the method provides / (guarantees) you will find the formula</U>.
