Solve - x16+1≥-5x2, for x without multiplying by a negative number. Then, solve by multiplying through by - 16.

-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
