Solution

x^{6} - 9 x^{3} + 8 \leq 0

Solution

1 \leq x \leq 2

+1

Interval Notation

[1, 2]

Solution steps

x^{6} - 9 x^{3} + 8 \leq 0

Factor

x^{6} - 9 x^{3} + 8 : (x - 1) (x - 2) (x^{2} + x + 1) (x^{2} + 2 x + 4)

(x - 1) (x - 2) (x^{2} + x + 1) (x^{2} + 2 x + 4) \leq 0

Identify the intervals

1 \leq x \leq 2

Popular Examples

((-x^2-1))/((9-2x))<= 0

\frac{( - x ^{2} - 1 )}{( 9 - 2 x )} \leq 0

((1+3x^2))/((2x^2-21x+40))<0

\frac{( 1 + 3 x ^{2} )}{( 2 x ^{2} - 21 x + 40 )} < 0

(x^2+2x-3)/(x^2+1)<0

\frac{x ^{2} + 2 x - 3}{x ^{2} + 1} < 0

((x-2)^2(x+1))/((x-3))>0

\frac{( x - 2 ) ^{2} ( x + 1 )}{( x - 3 )} > 0

((x+1))/(((x-1)^2))<= 1

\frac{( x + 1 )}{( ( x - 1 ) ^{2} )} \leq 1
