Rachel is 5 years old, her mother is 29 years old, and her grandmother is 54 years old.
In how many years will the sum of their ages be equal to 100?​

All you have to do is add the years together.

(5+29)+54

34+54=88

No, the sum is equal to 88, not 100.

sorry if this doesn't help

  ((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
