What are the roots of the polynomial equation x^3-7x=6x-12? use a graphing calculator and a system of equations.
a .–6, 6
b. –4, 1, 3
c. –3, –1, 4
d. 1, 3

The roots are x = -4, 1 and 3.

B is the correct option.

Step-by-step explanation:

We have to find the roots of the polynomial

We can find the roots by forming a system of equations and with the help of a graphing calculator.

The system of equations for the given polynomial:

Now, we graph these equations in the xy-plane. The x-coordinate (s) of the intersection point will be the roots of the equation.

The graph is shown in the attached file.

The intersection points are (-4,-36),(1,-6) and (3,6). The x-coordinates are x = -4,1 and 3.

Therefore, the roots are x = -4, 1 and 3.

B is the correct option.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

where is abdul's work? don't see that anywhere posted : /
