Acomputer has a shape of a rectangular solid. find the volume of the computer, with dimensions of 4 inches by 4 inches by 5.6 inches. (helll)

Step-by-step explanation:

Given : The volume of the computer, with dimensions of 4 inches by 4 inches by 5.6 inches.

The volume of rectangular box having dimensions 'l' by 'b' by 'h'  is given by :-

Then, the volume of the computer with the given dimensions will be :-

Hence, the volume of the computer =

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

its (2) option
