Write the polynomial equation for - 1/5,-1/2,-4

(5x+1) (2x+1) (x+4)

Step-by-step explanation:

The factored from of a polynomial can be found from the zeros or x-intercepts of the graph.

The x-intercepts here are x = - 1/5, x=-1/2 and x = - 4. You can find the factors by finding the expression which solves for each value.

Since x = - 1/5 then the factor is 5x+1.

Since x = - 1/2 then the factor is 2x+1.

Since x = - 4 then the factor is x+4.

So the factored form is (5x+1) (2x+1) (x+4).
