Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 ((22•11x2) -  x) -  3  = 0  

Step  2  :

Trying to factor by splitting the middle term

2.1     Factoring  44x2-x-3  

The first term is,  44x2  its coefficient is  44 .

The middle term is,  -x  its coefficient is  -1 .

The last term, "the constant", is  -3  

Step-1 : Multiply the coefficient of the first term by the constant   44 • -3 = -132  

Step-2 : Find two factors of  -132  whose sum equals the coefficient of the middle term, which is   -1 .

-132    +    1    =    -131  

     -66    +    2    =    -64  

     -44    +    3    =    -41  

     -33    +    4    =    -29  

     -22    +    6    =    -16  

     -12    +    11    =    -1    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -12  and  11  

                    44x2 - 12x + 11x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

                   4x • (11x-3)

             Add up the last 2 terms, pulling out common factors :

                    1 • (11x-3)

Step-5 : Add up the four terms of step 4 :

                   (4x+1)  •  (11x-3)

            Which is the desired factorization..

hope this helps u .

Step-by-step explanation:

=44x^2 - x-3

apply this in formula -b +- b^2 -4ac/2a

=a=44 , b =-1 , c=-3

= -(-1) +- √1^2-4*44*-3/2*44

=1+-√529/88

=1+- 23/88

= x=24/88=3/11 or x=22/88=1/4
