He sum of four and the product of three and a number x.

The sum of four and the product of three and a number x is ...

Now we are dealing with an unknown figure,  

x

The statement goes;

The sum of  

4

and the product of  

3

and a number  

x

The word sum is represented by addition

The word product is represented by multiplication

Hence;

4 + 3 × x

4 + 3  x  →  Statement

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
