[ 1/3Inequality]
Assignment:Find the solution set of inequality (2.5x)*(2.5x)+(1.82x)*(1.82x) >= 8.09*8.09 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
( 2.5 * x ) * ( 2.5 * x ) + ( 1.82 * x ) * ( 1.82 * x ) >= 8.09 * 8.09 (1)
From inequality(1)：
x ≤ -2.616165 或 x ≥ 2.616165
The final solution set is :
x ≤ -2.616165 或 x ≥ 2.616165[ 2/3 Equation]
