100 POINTS plz dont answer unless you know how to solve this.

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  

1/2*qr*rs

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
