Sandra had 23 jelly beans. She ate 8 jelly beans by herself. She then gave an equal number of the remaining jelly beans to 3 friends. How many jelly beans did each friend get?

each friend got 5 jelly beans

Step-by-step explanation:

First take 23 - 8 and get 15. Next take 15 and divide that by 3, since there are three friends. % is your answer

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
