Explanation Given: The given inequality is 1 x + 2 > 2 . Calculation Simplify the given inequality. 1 x + 2 > 2 1 x + 2 − 2 > 0 1 − 2 x − 4 x + 2 > 0 − ( 2 x + 3 ) ( x + 2 ) > 0 Multiply the both of above inequality by − 1 . ( 2 x + 3 ) ( x + 2 ) < 0 ( If a > 0 , c < 0 , then a c < 0 ) Observe that the above inequality ( 2 x + 3 ) ( x + 2 ) < 0 holds when both ( 2 x + 3 ) and ( x + 2 ) have opposite sign
