Find the root(s) of f (x) = (x + 5)3(x - 9)2(x + 1). -5 with multiplicity 3 5 with multiplicity 3 -9
faust18 [17]

Answer:

  -5, multiplicity 3; +9, multiplicity 2; -1

Step-by-step explanation:

The roots of f(x) are those values of x that make the factors be zero. For a factor of x-a, the root is x=a, because a-a=0. If the factor appears n times, then the root has multiplicity n.

f(x) = (x+5)^3(x-9)^2(x+1) has roots ...

  • -5 with multiplicity 3
  • +9 with multiplicity 2
  • -1

MrMuchimi
<span>The easiest way is probably noticing that the plane flies 180 miles farther than the car in the same time. And...the car goes 90 mph slower. If you imagine that they started at the same point...that means that the two trips went on for two hours (2 hours x 90 mph faster = 180 miles farther). </span>
