Hello,
A cubic polynomial with -2,1,2 as roots is
f(x)=k*(x+2)(x+1)*(x-2)=k(x²-4)(x+1)=k(x^3+x²-4x-4)
Looking the answers ==>k=1
==>Answer A
Answer:
2(w+6)
Step-by-step explanation:
This formula means that a(n) for n, when n is the term number, will give you the term. Meaning, we just have to plug in 55 for n.
a(55) = -1 + 3(55 - 1)
a(55) = -1 + 3 * 54
a(55) = -1 + 162
a(55) = 161
