Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  (10 - 29x) +  (2•5x2)

Step  2  :

Trying to factor by splitting the middle term

 2.1     Factoring  10x²-29x+10 

The first term is,  10x²  its coefficient is  10 .
The middle term is,  -29x  its coefficient is  -29 .
The last term, "the constant", is  +10 

Step-1 : Multiply the coefficient of the first term by the constant   10 • 10 = 100 

Step-2 : Find two factors of  100  whose sum equals the coefficient of the middle term, which is   -29 .

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -25  and  -4 
                     10x² - 25x - 4x - 10

Step-4 : Add up the first 2 terms, pulling out like factors :
                    5x • (2x-5)
              Add up the last 2 terms, pulling out common factors :
                    2 • (2x-5)
Step-5 : Add up the four terms of step 4 :
                    (5x-2)  •  (2x-5)
             Which is the desired factorization

Final result :

  (2x - 5) • (5x - 2)
