The speed limit on the road is 55 mph. the police officer is using a radar device to monitor speed. he allows people to exceed the limit by 5 mph or drive under the limit by 10 mph without giving them a ticket. write a compound inequality representing the speed which drivers can travel without getting a ticket.

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
