What are the roots of the polynomial equation x3 - 6x = 3x2 - 8? use a graphing calculator and a system of equations.
a. –40, –4, 5
b. –5, 4, 40
c. –4, –1, 2
d. –2, 1, 4

d : 4, 1, -2.

Step-by-step explanation:

There's no need for a calculator in my opinion because we can use the rational root theorem which states that the equations of this form:

Have rational roots, than the roots are of the form:

Rewriting the equation we have:

c
