The sixth graders at the middle school are going on a field trip to the aquarium. They will
spend 4 1/4 hours there, but 1/2 of an hour will
be used for lunch. How much time will the
students have to explore the aquarium?

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  

c. 4 1/4 pounds
