Let h= -150sin(0) + 260. This equation describes the height , in feet above the ground, of a point on the end of a blade of a wind turbine as a function of the angle of rotation of the blade. The point starts directly to the right of the center of the windmill. Describe the wind turbine and how it is spinning.

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
