Consider that the roots of a cubic equation with integral coefficients are 1, −2, and 3.
which choice is a factor of the cubic equation?
a) x + 2
b) x + 1
c) x + 3
d) x − 4

The answer is option A) X + 2

Step-by-step explanation:

Any polynomial of order n can be expressed in terms of their roots in factors of the form

(x-a)(x-b)(x-c)(x-d) = 0

Where a,b,c,d,... are the roots of the polynomial

In the example shown

(x+2) = (x-(-2))

And -2 happens to be the root of the polynomial in question

range is infinite on both x and y axis positive and negative
