term. Explain your steps and show any work
in finding the solution,
25x3 +__x² - x - 4
Solution: (x + 4)(5x + 1)(5x – 1)

100x^2+x-4

Step-by-step explanation:

x +  (4 • (5x + 1) • (5x - 1))x +  4 • (5x + 1) • (5x - 1)Factoring  100x2+x-4 The first term is,  100x2  its coefficient is  100 .The middle term is,  +x  its coefficient is  1 .The last term, "the constant", is  -4 Step-1 : Multiply the coefficient of the first term by the constant   100 • -4 = -400 Step-2 : Find two factors of  -400  whose sum equals the coefficient of the middle term, which is   1 .      -400    +    1    =    -399      -200    +    2    =    -198      -100    +    4    =    -96      -80    +    5    =    -75      -50    +    8    =    -42      -40    +    10    =    -30      -25    +    16    =    -9      -20    +    20    =    0      -16    +    25    =    9      -10    +    40    =    30      -8    +    50    =    42      -5    +    80    =    75      -4    +    100    =    96      -2    +    200    =    198      -1    +    400    =    399
