Briefly discuss the differences between the ordinal version of the results (Thread Wear) and the continuous (numerical) version of the results (Thread Wear Measured).

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

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

a is 8.b is 10.c is 10.5. d is -.5
