After a weekend trip to universal studios a group of student were asked how many times they rode the hulk the values are 1,4,5,2,1,1,2,3,3,8,2

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.
