    -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
