WebSolution:Factor the numerator and the denominator of the given inequality.x3+ 1 = (x + 1)(x2- x + 1) and x2- 9 = (x - 3)(x + 3) Arrange all the three zeros on the number and in order from smallest to the largest as follows. - 3 - 1 3 Select a value of x in the interval (-∞ , - 3) and use it to find the sign of the rational expression. WebMultiplying / dividing by a negative reverses the relation between the sides of the inequality. You can see this is you use an inequality containing only numbers. For example: Start with 4 < 12-- Multiply by -2 and you get: -8 < -24 which makes no sense as -8 is now larger than -24. -- Reverse the inequality: -8 > -24.
