What is the common ratio between successive terms in the sequence? 2, –4, 8, –16, 32, –64, –2 –6 6 2

-2

Step-by-step explanation:

You multiply each term by -2 to get the next term.

To find this for this sequence, divide the term on the right by the term on the left.

8 / -4 = -2              or          -4 * -2 = 8

-16 / 8 = -2             or         8 * -2 = -16

32 / -16 = -2           or         -16 * -2 = 32

-64 / 32 = -2           or         32 * -2 = -64

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
