What is the solution set of the inequality x5 + x4 - 6x3 + x2 + x - 6 ≥ 0?

A) [-3, -1], [-1, 2]
B) [-3, -1], [2, ∞)
C) (-∞, -3] , [-1, 2]
D) (-∞, -3], [2, ∞)

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
