    Answer:

    100x^2+x-4

    Step-by-step explanation:

    1. x +  (4 • (5x + 1) • (5x – 1))
    2. x +  4 • (5x + 1) • (5x – 1)
    3. Factoring  100×2+x-4
    5. The first term is,  100×2  its coefficient is  100 .
    6. The middle term is,  +x  its coefficient is  1 .
    7. The last term, “the constant”, is  -4
    9. Step-1 : Multiply the coefficient of the first term by the constant   100 • -4 = -400
    11. Step-2 : Find two factors of  -400  whose sum equals the coefficient of the middle term, which is   1 .
    13.      -400    +    1    =    -399
    14.      -200    +    2    =    -198
    15.      -100    +    4    =    -96
    16.      -80    +    5    =    -75
    17.      -50    +    8    =    -42
    18.      -40    +    10    =    -30
    19.      -25    +    16    =    -9
    20.      -20    +    20    =    0
    21.      -16    +    25    =    9
    22.      -10    +    40    =    30
    23.      -8    +    50    =    42
    24.      -5    +    80    =    75
    25.      -4    +    100    =    96
    26.      -2    +    200    =    198
    27.      -1    +    400    =    399
