What is the common difference for this arithmetic sequence? 54, 50, 46, 42, 38, A. 34 B. 4 C. 54 D. -4

-4

Step-by-step explanation:

Take the second term and subtract the first term

50 -54 = -4

We can check by taking the third term and subtracting the second term

46-50 = -4

The common difference is -4

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
