x^3+x^3-x-1>0

Solution

x^{3} + x^{3} - x - 1 > 0

Solution

x > 1

+1

Interval Notation

(1, \infty)

Solution steps

x^{3} + x^{3} - x - 1 > 0

Rewrite in standard form

2 x^{3} - x - 1 > 0

Factor

2 x^{3} - x - 1 : (x - 1) (2 x^{2} + 2 x + 1)

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

Identify the intervals

x > 1

(x^2-4)(x^2-9)>= 0

(x^{2} - 4) (x^{2} - 9) \geq 0

m^{2} =< \frac{2}{3}

(x^2-12x+32)(x-1)-10(x-8)>0

(x^{2} - 12 x + 32) (x - 1) - 10 (x - 8) > 0

\frac{6}{x - 2} > - x - 3

((-2x-1)}{(x-2)}+\frac{(x+1))/x <=-1/2

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