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.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
