At a farm, four employees harvest 48 pounds of food over a certain number of hours. Each employee works the number of hours shown. Employee A6 Employee B :4 employee C:8 employee D:8 The number of pounds of food harvested by each employee is potential to the number of hours worked.

A harvest = 11 pound (Approx)

B harvest = 7 pound (Approx)

C harvest = 15 pound (Approx)

D harvest = 15 pound (Approx)

Step-by-step explanation:

Given:

A - 6

B - 4

C - 8

D - 8

Total harvest = 48 pound

Computation:

Total hour = 6+4+8+8

Total hour = 26 hour

A harvest = 48(6/26)

A harvest = 11 pound (Approx)

B harvest = 48(4/26)

B harvest = 7 pound (Approx)

C harvest = 48(6/26)

C harvest = 15 pound (Approx)

D harvest = 48(6/26)

D harvest = 15 pound (Approx)

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
