Answer:

(x-3)*(4x+1)

Step-by-step explanation:

Factoring  4x2-11x-3

The first term is,  4x2  its coefficient is  4 .

The middle term is,  -11x  its coefficient is  -11 .

The last term, "the constant", is  -3

Step-1 : Multiply the coefficient of the first term by the constant   4 • -3 = -12

Step-2 : Find two factors of  -12  whose sum equals the coefficient of the middle term, which is   -11 .

     -12    +    1    =    -11    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -12  and  1

                    4x2 - 12x + 1x - 3

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

                   4x • (x-3)

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

                    1 • (x-3)

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

                   (4x+1)  •  (x-3)

            Which is the desired factorization

Final result :

 (x - 3) • (4x + 1)
