Answer:
−1.13348172≤x≤1.13348172
Step-by-step explanation:
For this problem
Add −5x2 to both sides of the inequality.
−x16 + 1 + 5x2≥0
Convert inequality to an equation.
−x16 + 1 + 5x2 = 0
Factor −x16 + 1 + 5x2
Set the factor equal to 00.
x16−5x2−1 = 0
x≈ − 1.13348172,1.13348172
so,
x≤ − 1,13348172
−1.13348172≤x≤1.13348172
x≥1.13348172
−1.13348172≤x≤1.13348172
