good day

Answer 2

Answer:

Given: x,(x-4),(x+5)

To Find: Which equation have the factors x,(x-4),(x+5)

Step-by-step explanation:

Let equation is P(x),then P(x) can be written as:

P(x) =x*(x-4)*(x+5)

P(x) = x*(x^2+(-4+5)x+(-4)(+5)]

P(x) = x*(x^2+(1)x+-20]

P(x) = x*(x^2+x-20)

P(x) = x^3+x^2-20x

Put x is an equation so;

P(x) =0

Means;

P(x) = x^3+x^2-20x=0

x^3+x^2-20x=0

is the correct answer.

I Hope This Help You.
