Textbook Problem

In Exercises 18 to 28, first solve each inequality. Then draw a number line graph of the solutions. x ( x + 2 ) < x ( 2 − x ) + 2 x 2

To determine

To solve:

The following ineqaulity and draw the number line,

x(x+2)<x(2x)+2x2

Explanation

Consider the following inequality,

x(x+2)<x(2x)+2x2

Use distributive property on the both sides of the given inequality to get the following,

x(x+2)<x(2x)+2x2xx+x2<x2xx+2x2x2+2x<2xx2+2x2x2+
