Hurry 4. Well-known pendulums such as those used in grandfather clocks sometimes
need to be adjusted to keep an accurate time. The formula 1 = 27. bis
used when tuning, or adjusting, these clocks, and includes the acceleration
due to gravity in feet per second squared (g). How long is the period of a
pendulum with a length of 128 feet and an acceleration due to gravity of 32 feet
per second squared? Use 3.14 for .

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
